Chapter 12.2, Problem 38E

Profit Because of sales by a competing company, your company’s sales of virtual reality video headsets have dropped, and your financial consultant revises the demand equation to

p = 800 q 0.35 , where q is the total number of headsets that your company can sell in a week at a price of p dollars. The total manufacturing and shipping cost still amounts to $100 per headset.

a. What is the greatest profit your company can make in a week, and how many headsets will your company sell at this level of profit? (Give answers to the nearest whole number.) b. How much, to the nearest $1, should your company charge per headset for the maximum profit?

| + 3. (5.7.12) On June 2, 2010 USA Today reported a story from Bloomberg News that said that the total price tag for the project to build the new F-35 Joint Strike Fighter would be 65% higher than the original $232 billion estimate. The cost now is estimated to be $382 billion. The total cost of each plane would be $112.4 million, up 81% from the original $62 million. The cost to produce each plane would be $92.4 million, about 85% higher than the original estimate of $50 million. a. Check the arithmetic to see that the three percentage increases reported are correct. b. Can you explain how the project cost can have increased by just 65% when the overall total per plane increased by 81% and the construction cost alone increased by almost 85%? 4. (5.7.3) Check that your own GPA from last semester has been computed correctly using the rules in effect at YSU. If you are in your first semester and don't yet have a GPA, imagine the grades you expect at the end of this semester and figure…
