Jose will spend at most 28 on gifts. So far, he has spent 15. What are the possible additional amounts he will spend?

Use for the additional amount (in dollars) Jose will spend.
Write your answer as an inequality solved for c

Let c be the additional amount Jose will spend.

The total amount Jose will spend is c + 15.
The problem states that he will spend at most 28.
So the inequality is c + 15 ≤ 28.
