Question

Keith has $500 in a savings account at the beginning of the summer. He wants to have at least $200 at the end of the summer. He withdraws $25 per week for food, clothing, and movie tickets. How many weeks can Keith withdraw money from his account?

Answer 1

`12` weeks

Explanation:

If Keith starts with `$500` and wants to end with (at least) `$200`
he can withdraw up to `$500-$200=$300`

If he withdraws `($25)/"week"` the `$300` will last
`color(white)("XXX")($300)/(($25)/"week")= 12 " weeks"`
