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?

55
60
130
150

Answer 1

60

Explanation:

Substitute 50 for y in the formula

5x+10y=800

5x+10*50=800

5x+500=800

5x=800-500

5x=300

x=300/5

x=60

Answer 2

60

Explanation:

5x+10y = 800

5x+10(50) = 800

5x+500 = 800

5x = 800-500

5x = 300

x = 300/5

x = 60

60 small vehicles were washed in total.

proof: 5x+10y = 800

5(60) +10(50) =800

300 + 500 = 800

800 = 800
