<u>Note: We are not given the weekly fee, but I'll assume it as $80 only to be able to solve the problem and explain the procedure.</u>
Answer:
<em>Ms. White will pay $110 if she drives 100 miles</em>
Step-by-step explanation:
Ms. White wants to rent a car for a week. It costs a weekly fee of $80 plus a $0.30 fee per mile driven.
If we call m = the number of miles driven by Ms. White during the week, then the cost of renting the car is:
C(m)= 80 + 0.30m
If Ms. White drives m=100 miles during the week, then the cost is:
C(100)= 80 + 30
C(100)= $110
Ms. White will pay $110 if she drives 100 miles
