The cost of renting a car for a day is $0.50 per mile plus a $15 flat fee.

A) Write an equation to represent this relationship. Let x be the number of miles driven and y be the total cost for the day.

Answer 1

y=0.50x+15

Explanation:

Total cost = 0.50x+15

If y =total cost of renting the car, then y=0.50x+15

cost for 1st car = 15 + 0.50x

cost for second car = 25 +0.25x

For same cost

15 +0.50x = 25 +0.25x

0.25x = 10

x = 40 miles

Answer 2

y = 15 + .50(x)
or
y = .50(x) + 15
btw the parenthesis are not needed
