Question 474323: Sales = 0.15x – 28
In this case, the values are given in thousands (i.e., the cost of making an
ividual e-reader will be $150 [0.15 × 1,000], with $28,000 [28 * 1,000] in constant charges).
Answer the following questions based on the given regression equation:
1.Using the graphing program that you downloaded from www.padowan.dk/graph, graph the sales equation. Discuss the meaning of the x- and y-axis values on the graph. (Hint: Label the axis with the Text tool in the graphing program.)
2.Based on the results of the graph and the sales equation provided, discuss the relationship between sales and number of e-readers produced. (Hint: Consider the slope and y-intercept.)
3.If the company does not sell a single e-reader, how much is lost in sales? Mathematically, what is this value called in the equation?
4.If the company sells 5,000 e-readers, how much will the company make (or lose) in sales?
5.If sales must equal 100 thousand, how many e-readers will your company need to sell? (Round up to the nearest e-reader.)
6.If your company is hoping to break even, how many e-readers will need to be sold to accomplish this? (Round up to the nearest e-reader.)
