Question

Jim will spend at most $27

 on gifts. So far, he has spent $19

. What are the possible additional amounts he will spend?

Use 

c

 for the additional amount (in dollars) Jim will spend.

Write your answer as an inequality solved for c

.

Answer 1

So we have the $19 already spent and c, the cash left over Jim's still willing to spend, and that totals $27 at most:

19 + c ≤ 27

To isolate and find c, we need to subtract 19:

19 + c - 19 ≤ 27 - 19

c ≤ 8
