Customers can pay $20 to rent a compact car for the first day plus $8 for each additional day, or they can rent the same car for $50 the first day and $5 for every additional day beyond that.

Raquel Greer · Answer 1

They would be the same after 10 days.

Step-by-step explanation:

In order to find this, we must first create two equations. Let x be the number of days that are rented. We'll first create an equation for the first company. Since it costs $8 per day, let 8 be the coefficient of x and 20 be the constant.

y = 8x + 20

Now, do the same with the second company.

y = 5x + 50

Now that we have these, set them equal to each other to get the answer.

8x + 20 = 5x + 50

3x + 20 = 50

3x = 30

x = 10
