Question

the total rental income for U-Drive rental car company was $520 for one day. They rent cars for $40 per day and vans for $60 per day. If they rented 7 cars that day, how many vans did they rent?

Answer 1

To solve this, you can set up an equation to model this situation:
`40x+60y=520`. In this equation, x is the number of cars rented that day and y is the number of vans. The number of cars rented is known (7) so you can plug 7 into the equation and then solve for y.

`40(7)+60y=520`

`280+60y=520`

`60y=240`

`y=4`

The answer is 4 vans.
