Question

A parking garage charges ​$4.004.00 for the first hour and ​$3.503.50 for each additional hour. If a customer gave the parking attendant ​$3030 for parking from 10 A.M. to 3 P.M.​, how much did the garage​ charge?

Answer 1

garage cost = $ 12

Step-by-step explanation:

given,

garage charge for first hour = $ 4.00

and for every additional hour = $ 3.50

customer pays = $ 30

garage charges = ?

time for which car was parked = 5 hrs

total charge = garage cost + first hour charge + 4 hour charge

$ 30 = garage cost + $ 4.00 + $ 3.50 × 4

garage cost = $ 30 - $ 18

garage cost = $ 12

hence, the garage cost comes out to be $ 12
