Question

At New York City's LaGuardia airport, one parking garage charges a onetime transportaton fee of $2.75 plus $22 for indoor parking per day. How many days has a car been parked at this location if the parking charge is $134.75?

Answer 1

x stands for number of days
22 + 2.75x = 134.75
2.75x = 134.75 - 22
2.75x = 112.75
2.75x/2.75 = 112.75/2.75
x = 41

check..
22 + 2.75x = 134.75
22 + 2.75(41) = 134.75
22 + 112.75 = 134.75
134.75 = 134.75 (correct)

ANSWER : The car was parked 41 days and was charged $ 134.75.
