Answer:
Number of small vehicles washed were 60.
Step-by-step explanation:
Soccer team collected $800 by charging $5 for the small vehicles and $10 for larger vehicles.
Amount collected was modeled by the equation
5x + 10y = 800
Where x = Number of small vehicles
y = Number of larger vehicles
If y = 5 then we have to calculate the number of small vehicles washed.
By putting y = 50 in the equation,
5x + 10(50) = 800
5x + 500 = 800
5x = 800 - 500
5x = 300
x =
x = 60
Therefore, number of small vehicles washed were 60.
