A rental car charges $25.00 per day plus $.30 for every mile the car is driven. Dale rents a car while his own car is being repaired, and he only drives it to and from work each day. Dale drives 7 miles each way to and from work. Write an expression to represents Dale's cost of renting a car for d days. Dale rents the car for 4 days. how much does Dale owe for the rental?

25d + .30(7+7)d = Cost

Insert 4 for d and calculate.

$116.80

To calculate Dale's cost of renting a car for d days, we can use the given information that the rental car charges $25.00 per day plus $0.30 for every mile the car is driven.

Let's break down the expression step by step:

1. Dale drives 7 miles each way to and from work, which means he drives a total of 7 miles + 7 miles = 14 miles per day.
2. The cost for driving these 14 miles in one day would be 14 miles * $0.30/mile = $4.20.
3. Additionally, Dale needs to pay the daily rental fee of $25.00.
4. Therefore, the expression for Dale's cost of renting a car for d days would be:
Cost(d) = (daily rental fee * d) + (cost per mile * miles driven per day * d)

Now, let's calculate Dale's cost for renting a car for 4 days:

Cost(4) = ($25.00 * 4) + ($0.30 * 14 * 4)
= $100.00 + $16.80
= $116.80

Therefore, Dale owes $116.80 for the rental.
