Question

John is saving $6 a week. He has already saved $28. How many weeks will it take John to reach his goal of $100?

Answer 1

12 weeks

Explanation:

If John is aiming to save $100, with $6 a week and he has already saved $28. The leftover amount to be saved is $100 - $28 = $72

In one week → $6

2 weeks → $12

3 weeks → $18

and so on..

`(72)/(6) = 12`

John will need 12 more weeks to save a total of $100.
