HELP PLZ I DONT GET IT
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?
What is your start up cost (cost of machine)?
Write a linear equation, y = mx + b for the total cost.

your rate of cost is .8x where x is how many loaves of bread you make.
Your startup cost is the amount of the machine $100
so your equation is y=.8x+100
kay you need to form an equation. Remember that in algebra, you use letters or symbols to represent different parts of the equation.
In this case, you have a constant. No matter how many slices or loaves of bread you make, you still have to pay $100 for the machine.
Any equation for this situation then is going to have to include +$100. If the cost of each loaf of bread is $0.80, your equation will be (for the cost of making loaves of bread):
C = $0.80n + 100
Where n is the number of loaves you want. If you want the cost of one loaf, it is simply ($0.80 x 1) + 100 which equals $100.80. If you wanted the cost of two loaves of bread it would be ($0.80 x 2) + 100 which equals $101.60, etc.
