Question

If a small boy, in 30 days, saved $1.00 to spend in your store, how much did he save each day?

Answer 1

Answer:

He saved 3.3 cents for 29 days and 4.3 cents for one day.

(This means a minimum of 3.3 cents each day)

Step-by-step explanation:

We divide the total amount saved by the number of days it took to save the money.

i.e $1.00 divided by 30 days

$\frac{1}{30} = 0.033$

He saves a minimum of $0.033 each day for 30 days

However, if he only saves $0.033 cents, he would have saved $0.99 on the thirtieth day.

0.033 x 30 = $0.99

This means he would be $0.01 short

Therefore, in order to have $1.00, he must save an extra $0.01 on one of the 30 days

This means he would save 0.033 + 0.01 = $0.043 for one day.

Where $1.00 = 100 cents

$0.033 = 3.3 cents

$0.01 = 1 cent

$0.043 = 4.3 cents

He saved 3.3 cents for 29 days and 4.3 cents for one day

3.3 x 29 = 95.7 cents

4.3 x 1 = 4.3 cents

95.7 + 4.3 = 100 cents

100 cents = $1.00

Answer 2

Answer:

3 cents for 29 days and 4 cents for 1 day

Step-by-step explanation:

1.00 dollar / 30 days = .03 cents

3 cents x 30 = .99 cents

3 cents for 29 days and 4 cents for 1 day
