Question

The cost to rent a construction crane is $750 per day plus $250 per hour of use. What is the maximum number of hours the crane can be used each day if the rental cost is not exceed $2500 per day ? Write amd solve the inequality

Answer 1

x = 7

Explanation:

x= number of hours

"cost is not exceed $2500 per day"

not exceed = less than

750+250x < 2500

250x< 2500-750

250x < 1750

x < 1750/250

x<7

7 hours

Answer 2

Let's use x to represent the number of hours since we don't know that.

750+250x<2500
Subtract 750 from both sides.
250x<1750
Divide both sides by 250.
x<7
The most hours that they can do is 7, or it can be less.
