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.
What is the domain of y=(x-2x+5)
