a
a. C(m) = .10(20m)
b. C(m) = m(20+.10)
C. C(m) = 20m +.10
d. C(m) = .10m + 20
2

Answer 1

d. C(m) = .10m + 20

Explanation:

Given the following data;

Initial rent fee = $20

Cost per mile = $0.10

To find the total cost;

The total cost is simply the sum of the initial rent fee and the cost per mile of the car.

Mathematically, the total cost is given by the expression;

T = I + cm

Substituting into the above formula, we have;

T = $20 + 0.10m
