At new york city's la guardia airport, one parking garage charges a onetime "transportation 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?

let no. of days parked = x

cost = 2.75 + 22x

=> 22x + 2.75 = 134.75

=> 22x = 132

=> x = 6 days
