Answer:

C = 15

Step-by-step explanation:

A + C = 20

15A + 10C = 225

There are several ways to solve this system; here is one of them.

Substitute into the second equation: 15A + 10(20 - A) = 225

Multiply, collect terms, and subtract 200 from each side: 5A = 25 => A = 5

Since C = 20 - A, C = 15
