- experiment why we need alloys: put two copper pennies into a glass of water. Add two teaspoon of salt and let the pennies sit there for a week. See what will happen to them
You want to buy a used car for $5500 and decide to borrow money from the Bank of Crooks.
You don’t need a down payment for this car and the Crooks uses this algebraic formula to determine your monthly payment.
1.13T = 15N + D
where T is the price of the car
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 is the down payment (ZERO)
- How many months will it take you to pay for this car (ans: 414.33 months)
- If you bought the car when you are 20 years old, how old will you be when you pay it off?
