Answer:
The correct answer is s = 27.
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
