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

5x+10y = 800
replace y by 50:  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
replace x=60 and y=50
       so; 5(60) +10(50) =800
             300 + 500 = 800
                     800 = 800

Answer 2

Answer:

60 in total

Step-by-step explanation:

proof: 5x+10y = 800

replace x=60 and y=50

      so; 5(60) +10(50) =800

            300 + 500 = 800

                    800 = 800
