Enrique predicts that he can make additional money from sales of accessories and services for computer products sold by his store. The table below shows predicted percent returns for such sales.

Question

Return on Store Sales
Product %
Accessories 5.0
Protection Plan 7.5
Maintenance and 2.5
repairs
For example, if the store makes x dollars (0.05) from selling accessories, Enrique predicts the store will make 0.05x dollars from selling accessories.
1. In January and February of this year, the store made $2500 from sales of accessories and services. Let x represent the amount the store will make from sales of computer products from March through December. Write an equation that represents the predicted amount y that the store will make from sales of accessories and services for the entire year. If Enrique predicts sales from accessories and services for the entire year will be $5000, about how much money must be made from computer product sales from March through December. Explain.
b.What are the slope and y intercept of the graph of the equation from a? What do the slope and y intercept represent this situation? Explain.

Answer 1

y = (.05 + 075 + .025)x = 0.15x
see what you can do with that.
