The cost of parking a car at the city lot is $4 for the first hour and x dollars for each additional hour or part of an hour. max parked his car for 6 hours and paid $8.50. find the value of x.

4+ x(5)=8.50    (we use 5 hours since the 1st hour is included in the 4 dollars)

4+5x=8.5      subtract 4 from each side

5x = 4.5      divide each side by 5

x=.9

x=$0.90
