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.
