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 5 x plus 10 y equals 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?

Vocaloid · Answer

They give you the equation 5x + 10y = 800

Where x = number of small vehicles and y = number of large vehicles

They tell you that the number of large vehicles was 50, so y = 50. Plug this into the equation and solve for x to get the number of small vehicles.
