Answer:

Explanation:

answer: owen can afford to keep and drive the car for 4 days.

The total owing on the car rental is R(d) = ($77.25/day)d + ($0.12/mile)m ≤ $330. Substitute 1 for d (that is, the rental is for 1 day) and 175 for m:

R(d) = ($77.25/day)(d days) + ($0.12/mile)(175 miles) ≤ $330

= $77.25d + $21 ≤ $330

This simplifies to $77.25d + $21 ≤ $330, or

$77.25d ≤ $309

Solving this by dividing both sides of the above equation by $77.25, we get

d = ($309)/($77.25) = 4
