Question

The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation 5x+10y=800 , where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total?

Answer 1

Answer: They washed 60 small cars.

Explanation:

5x + 10y = 800

y = 50

5x + 10(50)

5x + 500 = 800

Subtract 500 from each side

5x = 300

Divide each side by 5

x = 60
