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

Answer:  60

Step-by-step explanation:

Given : 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.

When y=50 , then we have

$5x + 10(50)= 800\\\\\Rightarrow\ 5x+500=800\\\\\Rightarrow\ 5x=300\\\\\Rightarrow\ x=\dfrac{300}{5}=60$

Hence, the number of small vehicles were washed in total = 60

Answer 2

10 x 50 = 500
800 - 500 = 300
5 x 150 = 300

Answer = 150
