Question

Your company needs to temporarily hire a programmer to work on a project. Two proposed payment schemes for this work are as follows:

* (1) A flat fee of $1,000, plus $20 per hour or (2) $25 per hour.
o Set up and solve an inequality that would enable your company to determine possible job lengths (in hours) for which the person is paid less according to plan 1 than for plan 2. I have these as y = 1000 + 20 * x and y = 25*x is this right? How do I graph these for part 3 using Pawodan Graph?
o (Hint: Set up two expressions and use an inequality to separate them for solving. Let x = the number of hours worked.)

Part III: Functions and Graphing

From Part II, express the two pay plans as a function of the number of hours worked (again, letting x = number of hours worked and changing each expression to a function).

1. Graph both functions.
2. Notice in the graph where one function is higher than the other, and interpret this in terms of which pay plan costs the company more (compared to the other plan) for certain numbers of hours worked.

Your graph will show shaded region where your company saves money. example: http://www.cramster.com/answers-jan-11/algebra/college-algebra-textbook-mic-time-takes-multiply-matrices-size-dete_1112967.aspx
