Answer 1

A)
`m=(350)/(25)`

Explanation:

We are trying to find how long it will take Carlos to have $500 TOTAL, so we need to subtract what he already has ($150) to get the value we want to divide by $25 to figure out how many months it will take him to save up the rest. The given answer above is just a simplified way of writing
`m=(500-150)/(25)`, if that makes more sense.
