Question 218824
A parking garage charges $1.75 for the first hour and $0.50 for each additional hour or part of an hour. What is the maximum length of time Tom can park in the garage if he wishes to pay no more than $4.25? 
------------------------------------------------------
Cost = 1.75 + 0.50(x-1)
4.25 >= 1.75 + 0.50x - 0.50
0.50x +1.25 <= 4.25
0.50x <= 3.00
x <= 6
