1.Idnia works at Euclid’s Electronics. She is paid a salary of $200 per week plus a commission of 5% of her sales during the week.

Question

Idnia is offered another job at Fermat's Footwear, where the pay is a salary of $100 per week and 10% commission on all sales. She asks
you to help her determine which job she should keep.

Create a linear system that represents the two options. Label the equations 1 and 2 ( /2TH)

Graph the equations ( 5/COMM)

State the method of graphing you will use _______________________( /1 COMM)

c) Analyze the graph and complete the questions below. ( /8APP)
i. Where the two lines cross is called the point on intersection, or the solution to the system. At what coordinates do the two lines cross?


ii. What does this coordinate represent in terms of Idnia's sales, and pay for the
week?

iii. If Idnia usually makes $1500 worth of sales per week, which job should she take? Explain.

iv. Explain how does the graph help Idnia determine which is the better job?

v. What does the point (1000, 250) represent on the graph

Answer 1

You are on your own for all that ( /2TH) and ( 5/COMM) stuff
Your 2 equations are:
Euclid's pay = 200 + .05s
Fermat's pay = 100 + .1s , where s is sales for each part

so graph
y1 = 200 + .05x
y2 = 100 +.1x

Answer 2

0.05x-0.05x+0.10x+200+100
0.10x+300
