Mth128a algebra: unit 6 part 2 test you must show/explain all of your work to get credit. alexis runs a small business and creates recordings of her friend’s skateboard stunts. she puts the recordings onto blu-ray and sells them online. she realized that the average cost of each blu-ray depends on the number of blu-rays she creates, because of the fixed cost. the cost of producing x blu-rays is given by b(x) = 1250 +1.75x 1) alexis wants to figure out the price to charge friends for the blu-rays. she doesn’t want to make money at this point since it is a brand new business, but does want to cover her costs. suppose alexis created 50 blu-rays. what is the cost of producing those 50 blu-rays? how much is it for each blu-ray? 2) alexis wants to make more than just 50 blu-rays eventually, once her business takes off. fill in the chart below to show costs at each level of production. # blu-rays 0 10 100 1,000 10,000 100,000 1,000,000 total cost cost per blu-ray 3) in words, explain why the average cost of the blu-rays seems to level off. 4) create an equation for the average cost per blu-ray of creating x blu-rays. 5) from the table above, use the data points to sketch a graph showing the average cost. (you can draw the graph by hand or use your computer). how does the graph show that the costs level off for each blu-ray?
