A rental car agency charges $15 per day plus $.11 per mile to rent a certain car. Another agency charges $18 per day plus 8 cents per mile to rent the same car. If they rent the car for one day how many miles will they have to be driven for the cost of a car from the first agency to equal the cost of a car from the second agency.

you're all wrong, you idiots. it's 100 miles.

15 + .11m = 18 + .08m

.11m = 3 + .08

.03 = 3

m = 100

To find the number of miles that need to be driven for the cost of a car from the first agency to equal the cost of a car from the second agency when rented for one day, we can set up an equation.

Let's assume the number of miles driven is represented by "m".

For the first agency, the cost of renting a car for one day is given by the equation:
Cost1 = 15 (daily rate) + 0.11m (cost per mile)

For the second agency, the cost of renting a car for one day is given by the equation:
Cost2 = 18 (daily rate) + 0.08m (cost per mile)

We want to find the number of miles (m) for which the two costs are equal:
Cost1 = Cost2

This can be written as:
15 + 0.11m = 18 + 0.08m

Now, let's solve this equation to find the value of "m":
0.11m - 0.08m = 18 - 15
0.03m = 3
m = 3 / 0.03
m = 100

Therefore, they will have to be driven for 100 miles for the cost of a car from the first agency to equal the cost of a car from the second agency when rented for one day.

67

the cost is the same for m miles if

15+.11m = 18+.08m

Now just solve for m.
