The daily cost of renting a car is $25.00 plus $0.30 per mile driven. What is the cost of renting the car for one day and driving at 75 miles?

The cost of renting the car for one day and driving at 75 miles = $ 47.5 .

Step-by-step explanation:

GIven: Daily cost of renting car = $ 25.00 + $0.30 per mile driven

Let x = Total distance traveled ( in miles).

Then total cost of renting (in $)= 25+0.30x

For x= 75 miles

The  total cost of renting (in $)= 25+0.30(75)

=25+22.5

= $47.5

Hence, the cost of renting the car for one day and driving at 75 miles = $ 47.5

x=10

y=4

8+10=18

7+4=11

18-11 = 7

Therefore, the answer is, 7.
