Thread: Slope Word Problem

1. Slope Word Problem

I have been working on a worksheet for my Algebra I class, and I have figured out all but a few problems relating to one question. Help is much appreciated.

A construction company charges $15 per hour for debris removal, plus a one-time fee for use of a trash dumpster. The total fee for 9 hours of service is$195.

Part a)
Write the point-slope form of an equation to find the total fee y for any number of hours?

part b)
Write the equation in slope-intercept form.

part c)
What is the fee for the use of a trash dumpster?

Thank-you for your time.

2. Here's a kick start.

Consider the slope-intercept form C = aN+b where C is total cost and N is the number of hours.

'a' is the hourly rate i.e 15 now all we need to do is solve for 'b'.

You are also told that (N,C) = (9,195) put this information back into the equation to solve for 'b'.
