Greg will spend at most 25 on gifts. So far, he has spent 13. What are the possible additional amounts he will spend?

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

To find the possible additional amounts Greg will spend, we need to subtract the amount he has already spent from the maximum amount he will spend. This can be written as:

25 - 13 ≤ c

Simplifying:

12 ≤ c

So the possible additional amounts Greg will spend are any amount greater than or equal to 12 dollars.
