NOT A MULTIPLE CHOICE QUESTION, I NEED AN ANSWER FOR ALL!!!
I. The Bread Machine (25 points)
In real life, you must often make choices about whether to buy something pre-made or make it yourself. There are many things to consider: quality of homemade vs. bought, expense, convenience, enjoyment of making something, etc. In this response, you will be looking at the choice of buying a bread machine or relying exclusively on store bought bread.

A. The bread machine you are interested in costs $100 with tax.
The ingredients to make one loaf of bread cost $0.80.
What is the rate of cost of one loaf of bread?

B. What is your start up cost? (cost of machine)

C. Write a linear equation, y = mx + b for the total cost.

D. Graph the equation on the graph provided. You may use either Point Plotting or Slope-Intercept. Be sure to locate at least 3 points. You may want to do this in pencil in case you decide to use more points later in the problem.

1. The decision you're looking at is buying a bread machine and the ingredients to make bread vs buying bread at the store.

B. What is your start up cost (cost of machine)?
$100

C. Write a linear equation for the total cost in form, y = mx + b.
Total cost is the cumulative cost for all loaves of bread since the machine was purchased.
You have the start-up cost plus the cost of each additional loaf of bread, so the total cost (Y) is:
Y = $100 + $0.80*x
where x is the number of loaves of bread.

D. Graph the equation on the graph provided.
