Car Rentals rents cars and trucks for $25 and $30 a day, respectively. Last Tuesday, they rented all but

7 rental vehicles and reported $195 in lost rent.

How many trucks were not rented last Tuesday?

Write the system of equations and solve for how

many trucks.

let x be the number of cars, and 7-x be the number of trucks.

25x + 30(7-x) = 195

25x + 210-30x = 195

5x = 15

x = 3

So, 3 cars were not rented. If 7 total vehicles were not rented, 7 - 3 cars = 4 Trucks

4 Trucks were not rented.

Step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
