Need help in working this problem - the cost of renting an edger is $16.50 for the first hour and $10.95 for each additional hour. How long can a person have the edger if the cost must be less than $55.00? (This is a question under the inequalities section)

16.50 + 10.95x < 55

Solve for x.

We tried that but was told that it was wrong.

10.95x < 38.5

x < 38.5 / 10.95

x < 3.5 = 3 hours

That's the only answer that makes sense. At about $11 an hour, the edger can only be rented for 3 hours.
