d) Consider other expenses related to their home, can they afford living there?
property tax: $3300/year; fuel for car: $5000/year
hydro, water, gas = $2600/year; Maintenance for house= $2000/year;
Maintenance for house= $3000/year; day care for two children=$9000/year
Cable, TV, internet, phone = $3750/year;
Insurance for car and house = $4000/year;
3300 + 2600 + 3000 + 3750 + 4000 + 5000 + 2000 + 9000
= 32650 Total expenses per year (goes up by 5% every year)
e) Calculate the total expenses (house related, child care, mortgage and car payments, excluding food) for the year and convert it to a monthly expenses. (ie. Divide by 12)
Annual total expenses 32650
Mortgage payment every year(475 x12) = 5700
Car payment every year (155 x 12) = 1860
Raymond and wife earns $48000/year
Total expenses 32650 + 5700 + 1860 = $55560/year
The Raymond family does not have enough money to pay for everything even if they don’t eat (really SAD). Expenses > Salary
f) Consider Raymond and his wife income, can they afford the new car and the new house even they don’t have to eat. Compare the two numbers (income and total expenses)
The Raymond family does not have enough money to pay for everything even if they don’t eat (really SAD). Expenses > Salary
- The situation now is similar to many families
- About 20% of all Toronto mortgage holders will lose their homes
g) If you were Raymond, will you move to Far Far Away? (NO, spend too much on gas, too exhausted after work to take care of kids) What are your choices to reduce expenses and/or increase income? List two alternatives for each.
- two ways to increase income
1) Get another job (Uber, work from home)
2) Downsizing – rent out their basement (about $1000 to $1200/month)
- two ways to reduce expenses
3) one parent stays home to take care of kids, no daycare
4) Prepare own meals, pack own lunch (left over)
5) Car pool with people in the area
6) Cut down on cell phone bills (usually close to $100/m, Kwok $35/m – voice, text, 4G data)

Raymond and his wife earn $48,000 (after tax) each year. They decide to spend $555,000 buying a townhouse in the town of Far Far Away.
Raymond and his wife are both 45 years old with two children (age 5 and 6).
They borrow money from the Bank of Kwok and this algebraic formula is used to calculate their payment since they do not need a down payment.
1.13T × 1.253 = 475N
where T is the price of the townhouse
1.13 is the 13% HST (thus 1.13T is the total cost you must pay)
N is the number of months for your payment; D = 0
1.13T × 1.253 = 475N
1.13 × 555000 × 1.25^3 = 475N
1.13 × 555000 × 1.95 = 475N
1222942.5 = 475N
1222942.5/475 = N
2574.61 = N (how many months to pay off his house)
2574.61 months/ 12 months = 214.55 years
(it will take Raymond 214.55 years to pay off his house)
- how old will Raymond be at that time? (ans: 259.55 years, dead over three times)
Right now, Raymond is 45 years old.
Raymond will be 45 + 214.55 = 259.55 years when he pays off his house
- how old will his kids be?
Older kid, age 6 now. S/he will be 6 + 214.55 = 220.55 years
Younger kid, age 5 now will be 5 + 214.55 = 219.55 years
In addition, they have to buy a car to drive to work since the town of Far Far Away is 90 minutes away from their offices. The car costs $28,000
Without a down payment, the car payment calculation is
1.13T × 1.553 = 155N
c) Calculate how many months it will take Raymond and his wife to pay off their car.
1.13T × 1.553 = 155N
1.13 x 28000 × 1.55 x 1.55 x 1.55 = 155N
1.13 x 28000 x 3.72 = 155N
117700.8 = 155N
117700.8/155 = N
759.36 months = N (or 63.28 years)
d) After the 1.553 factor, how much is the car now without a down payment?
e) Is this a good idea not to have a down payment for their townhouse and car? Explain.
e) Is this a good idea not to have a down payment for their townhouse and car? Explain.
- it is a bad idea
- end up paying a lot more for the product (perhaps twice as much)
- takes a LONG time to pay it off
- even if you have to work an extra job to earn more money

The Crook’s Store: Buy What You Want!!! NO MONEY DOWN, low monthly payment, GREAT DEALS!
Calculate the total cost of each item after all the adds on
e.g. Samsung Foldable Smart Phone, T = $3000
1.13T × 1.553
= 1.13T´ (1.55 ´ 1.55 ´ 1.55)
= 1.13T ´ 3.72
= 1.13 ´ 3000 ´ 3.72
= 12610.8
How much more do you have to pay?
12610.8 (after all the charges) – 3000 (original price) = $9610.8 wow
k) A gold chain, T = $550
1.13T × 1.253
1.13T × (1.25 × 1.25 × 1.25)
1.13T × 1.95
1.13 × 550 × 1.95
1211.92 (you will be paying more than twice the original price if you choose to pay later)
How much more do you have to pay?
1211.92 – 550 = 661.92 more than the original price
l) A designer outfit, T = $875
1.13T × 1.352
How much more do you have to pay?
m) A trip to Hawaii, T = $3875
1.13T × 1.352
How much more do you have to pay?
n) Two downhill ski passes at Blue Mountain, T = $125
1.13T × 1.094
How much more do you have to pay?
p) Two court side tickets to see NBA finals, T = $12500
1.13T × 1.213
How much more do you have to pay?
n) A used car, T = $5555
1.13T × 1.282
How much more do you have to pay?

Sangster Math, June 9, 2022
Different scenario:
Car = $3500
1.13 x T = 48 x N + D (down payment)
a) What if you increase your down payment to $1075. How many months will it take to pay off the car?
1.13 x T = 48 x N + D (down payment)
1.13 x 3500 = 48 x N + 1075 (down payment)
3955 = 48 x N + 1075
3955 – 1075 = 48 x N
2880 = 48 x N
2880/48 = N
60 = N (it takes 60 months to pay off the car)
60 months = 5 years
Original down payment
1.13 x 3500 = 48 x N + 643 (down payment)
3955 – 643 = 48 x N
3312 = 48 x N
3312/48 = N
69 = N (it takes 69 months to pay off the car)
b) What if you increase your monthly payment to $144, keeping the same down payment. How many months will it take to pay off the car?
1.13 x T = 144 x N + D (down payment)
1.13 x 3500 = 144 x N + 1075 (down payment)
3955 = 144 x N + 1075
3955 – 1075 = 144 x N
2880 = 144 x N
2880/144 =N
20 = N
c) What if you lower your monthly payment to $36. How many months will it take to pay off the car?
- is this a good idea to take so long to pay off a used car? Why?
(remember, you have to spend 5+ years to pay off the used car)
- It is a bad idea to take too long to pay for an used car
- (1) when a car is more than 8 years old, there are a lot of mechanical problems
- (2) you will end up spending more money to repair it
- (3) worth very little for a car that is 8+ years old
General idea:
- Japanese cars (Toyota, Hondas, Lexus, Acura, Nissan, Mazda) are good for at least 8 years without problems
- Domestic cars (Ford, GM, Chrysler) are good for 3 to 5 years without major problems
- European (BMW, Mercedes, Audi, VW) are good for 3 to 5 years. Very expensive to repair
- Electric cars or Hybrid vehicles – (battery is good for about 8 years, cost $20000 to replace the battery)
Right now, there are a lot of “Buy now and Pay later” companies
NOBODY
- What’s wrong with this no down payment, buy now pay later case?
- (1) you buy things they cannot afford
- (2) if the money is not paid back on time (within a year), very high interest will be charged (Best Buy charges 30% interest)
- (3) Vacation companies (Air Canada), initial fee $3000 for a week, $5000 within a year with charges
