Question

Leila wrote an equation to represent the revenue of a parking lot for one day. She let x represent the number of cars that paid to park and y represent the number of trucks that paid to park. If a car costs $8 per day, a truck costs $10 per day, and the total revenue for the day was $830, which equation could Leila use to represent the number of cars and trucks that paid to park that day?

Answer 1

Answer:

8x+10y = 830

Explanation:

The variable x represents the number of cars that paid to park.  The variable y represents the number of trucks that paid to park.

Since parking a car costs $8 per day, the expression to represent the cost of parking all x cars that parked that day is 8x.

Since parking a truck costs $10 per day, the expression to represent the cost of parking all y trucks that parked that day is 10y.

The expression for the total cost is 8x+10y.

We know the total was $830; this gives us the equation

8x+10y = 830.

Answer 2

8x+10y=830< this is your equation
