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?
0.8

B. What is your start up cost? (cost of machine)
$100(tax)= $107

C. Write a linear equation, y = mx + b for the total cost.
$107.80= 0.8(1) + 107

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.

You seem to have provided all of the answers, except for the graph.

See the graph attached.

Financially and economically, assuming that bread costs $2 per loaf
in the store, store-bought bread is cheaper for the first 84 loaves.
After that, it becomes more cost-effective to make it at home.

The other factors involved are more difficult to quantify, measure,
evaluate, and compare.
