Three kids really like M&M. They eat a different amount each day following these formulae:
Mini Kwok= he eats twice as many as the previous day (2x)
Hyper = she eats three times as many as the previous day (3x)
Jumpy = she eats one more than the previous day (+1)
Whinny = he eats [to the power two] of the previous day (A2)

a) Complete the chart above, and calculate how many each child eat after one week
b) If each child gains 0.25Kg after 20 M&M, calculate the weight gain on each kid. Use cross multiplication
c) If 15 M&M costs $0.50, how much did each pay for the candy?

How to turn money into wealth?
Saving regularly is very important, especially when you receive an allowance regularly and want to buy something expensive [e.g. a car, a computer]
Assuming you have your parents to do some housework every week (e.g. take out recycles, vacuum the house, do the dishes, fold the laundry, tidy your room etc), you get $40 per month. Say, half of it will be spent on greasy cafeteria food, and you should save half of the allowance.
Month | Allowance | Total Saving [you save half of the allowance] |
Jan
| $40 | $20 |
Feb
| $40 | $20 (from Jan) + $20 = $40 |
Mar
| $40 | $40 (from Jan/Feb) + $20 = $60 |

Determine how much allowance you receive from your parents each year, and how much is saved.
List three ways you can minimize your expenses and save more.
With all the money you have saved up each year, it is a good idea to invest in one good stock so money can grow.
Each year, a good stock can grow at 1.022 of the original investment. See example below
Age | Annual Saving | Total after stock appreciates |
12 | $240
| $240 x 1.022 = $249.69 |
13
| $240
| ($240 + 249.69) x 1.022 = $509.27 |

Calculate how much you are able to save (with the stock appreciation) when you are 21.
If you want to buy a used car that costs $5000, do you have enough money to buy it?
