Me solve this 7th grade math problem, you!

The correct answer is s = 27.

Step-by-step explanation:

This problem already gives us an equation so all we need to do is plug in the numbers:

c = 39.95 + 0.15(s + r) becomes 53.45 = 39.95 + 0.15(s + 63). Now to solve:

53.45 = 39.95 + 0.15(s + 63)

13.50 = 0.15(s + 63)                     Subtract 39.95 from both sides

13.50 = 0.15s + 9.45                    Distribute 0.15 to s and 63

4.05 = 0.15s                                 Subtract 9.45 from both sides

27 = s                                           Divide both sides by 0.15

Hope this helps,
