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

8x + 10y = $830

Explanation:

8x + 10y = total revenue

if the total revenue is 830 then you can equate the above formula to 830 to give

8x + 10y = $830

Answer 2

The required equation is
`8x+10y = 830`.

Explanation:

Consider the provided information.

As it is given that variable x represents the number of cars that paid to park and variable y represents the number of trucks that paid to park.

The cost of parking a car is $8 per day, the expression to represent the cost of parking x cars per day is 8x.

The cost of parking a truck $10 per day, the expression to represent the cost of parking y trucks per day is 10y.

The total revenue for the day was $830.

Thus, the equation represent the number of cars and trucks that paid to park that day is:

`8x+10y = 830`

Hence, the required equation is
`8x+10y = 830`.
