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.
