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?

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.

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
