Example 3

The parking fee at a public garage is $5 for the first hour and $3 for each additional hour (or fraction of the hour). How long can you park if you have $14 to spend on parking? Let h represent the number of additional hours after the first hour.

Step 1. Write an inequality to represent the situation.

Price of parking for first hour + $3 times each additional hour (h) ? $14

Step 3. Answer the question.

You can park up to 3 additional hours, for a total of 4 hours.
