Question

Currently, there are 420 cars in the parking lot. Campus security needs the set up for an event. They have only ten minutes to make sure that the parking lot has only 50 cars. Write an equation that would allow them to calculate x, the number of cars to leave the parking lot each minute.

Answer 1

The number of cars to leave parking lot each min = 37

Explanation:

Numbers of cars in parking lot = 420

Time required to make sure that parking lot have only 50 cars = 10 minutes

So ,number of cars to leave parking lot = 420 - 50 = 370

∵ 10 min required to leave number of cars = 370

∴ For 1 min , number of cars to leave =
`(370)/(10)` = 37

Hence The number of cars to leave parking lot each min = 37 Answer
