Answer:
C = 20.65 + 0.75M
Explanation:
Given in the question that,
standard charge by the rental company = S = 16.95 + 0.60M
insurance charge by the rental company = I = 3.70 + 0.15M
Total charge C = S + I
16.95 + 0.60M + 3.70 + 0.15M = C
20.65 + 0.75M = C
So the equation which represent total charge that includes insurance in terms of M is
C = 20.65 + 0.75M
