A truck company charges $30 to rent a moving truck for the day, plus 5 cents for every mile driven during the day. The function f(x)=0.05x+30 represents the total cost for the moving truck for one day's rental where x is the number of miles driven.

Answer 1

Part A: $32.10

Part B: 156 miles

Explanation:

Part A:

$0.05 per mile. 0.05 times 42 = $2.10

30 + 2.10 = $32.10

Part B:

The rent cost a day is $30

37.80 - 30 = $7.80

7.80 is the money for miles

7.80 divided by 0.05 = 156 miles
