Question

Merry is certain that every time she parks in the municipal garage it cost her at least $2.20. If the garage charges .45 plus .25 for each half hour, how long is merry's car parked?

Answer 1

The time for which parking charge taken is 3.5 hours

Explanation:

Given as :

The total cost paid by Merry for car parking = $2.20

The charge taken by garage for parking is as ( $0.45 ) +( $0.25 for each half hour)

Let the Time taken as half hour = x

So, According to question

0.45 + 0.25 × x = $2.20

Or, 0.25 × x = $2.20 - $0.45

I.e 0.25 × x = $ 1.75

∴ x = $ (
`(1.75)/(0.25)` = 7

So,Total time spend =
`(7)/(2)` = 3.5 hours

Hence The time for which parking charge taken is 3.5 hours Answer
