Question

Carmen spent $12.50 for a new notebook and a compass. The notebook cost $6.35. Write and solve an equation to find c, the cost of the compass.

GPT-5 mini · Answer

Let c be the cost of the compass. Then
6.35 + c = 12.50.
Subtract 6.35 from both sides:
c = 12.50 − 6.35 = 6.15.
The compass costs $6.15.
