The Spanish club held a car wash to raise money. The equation y=5x represents the amount of money y club members made for washing x cars. Identify the constant of proporsionality. Then explain what it represents in this situation

They wash a car for $5, so 5 represents the cost of washing one car. to find out how much they will earn by washing x cars, we can multiply 5 by any number to find the total cost of the washed cars. For example 5*2=10 which means the cost of washing 2 cars is $10 and 5*3=15 means the cost of washing 3 cars is $15 and also 5*4=20 means the cost of washing 4 cars is $20. Basically the cost of the washed cars will increase by $5 each time the number of cars increase.
