Question

Do you have 135$ in a savings account and save $12 per week your friend has $95 in a savings account and save $20 per week how many weeks will it take for you and your friend have the same balance?

Answer 1

5 weeks.

Explanation:

If w is the number of weeks, apply algebra.

So think about what would be the total money saved, or the same thing as the Money in saving account + Money saved per week × Number of weeks

For you, this would be 135 + 12w

For your friend, 95 + 20w

So then, 135 + 12w = 95 + 20w

1) 135- 95 = 20w - 12w

2) 40 = 8x

3) X= 5 (8 times 5 is 40)

Therefore, it will take 5 weeks for you and your friend to have the same balance.
