A manufacturer measures the number of cell phones sold using the binomial 0.015c+2.81. She also measures the wholesale price on these phones using a binomial 0.011c+3.52. Calculate her revenue if she sells 100,000 cell phones. Revenue = (numberofcellphones)(wholesaleprice ) = (0.015c+2.81)(0.011c+3.52)
