Question

1. a car rental service charges $100 plus $10 per mile driven. write an equation for the total cost $c$ based on miles $m$ driven. a. $c = 10m + 100$ b. $c = 100 - 10m$ c. $c = 10 + 100m$ d. $c = 100m + 10$

Explanation:

Step1: Identify fixed cost

Fixed cost = $\$100$

Step2: Identify variable cost

Variable cost = $10m$ (cost per mile × miles)

Step3: Sum costs for total C

$C = 10m + 100$

Answer:

a. $C = 10m + 100$
