Question

a parking garage charges ​$3.50 for the first hour and ​$2.25 for each additional hour. if a customer gave the parking attendant ​$50 for parking from 10 a.m. to 3 p.m.​, how much did the garage​ charge?

Answer 1

$3.50 for the first hour.... $2.25 for every additional hour he stays from 10 am to 3 pm... 

10 am - 3 pm is 5 hours

$2.25 x 4 = $9 

$9 + $3.50 = $12.50

now add all that...
$12.50 + $50 = $62.50 is the total
