student : a sporting good store sells basketball shorts for \$8. at this price their weekly sales are approximately 100 items. research says that for ever \$2 increase in price, the manager can expect the store to sell five fewer pair of shorts. determine the maximum revenue the manager can expect base on these estimate. what selling price will get that maximum revenue, and how much shorts will be sold
tutor3 : ok thanks
tutor3 : please wait for sometime
student : ok
student : question hard?
tutor3 : no
tutor3 : No a bit calculative
tutor3 : ok here is the solution
tutor3 : Let the price be(8+2*k)
tutor3 : the sales price is (100-5*k)
tutor3 : so revenue is(8+2*k)(100-5*k).You maximise this quadratic function and you get k=8
tutor3 : so revenue eared is 60*24=1440 and number of shirts sold is 60
tutor3 : thanks
student : where are u getting the 60?
tutor3 : (100-5*k)=(100-5*
student : their a missing image
student : all i see is (100-5K)=(100-5x???)
student : i get it
