sumate the amount of money she pays, in dollars, when using k kilowatt hours of electricity. She

looks at her previous power bills and finds that she paid $45.83 for 550 kilowatt hours of electricity in November

and $93.57 for 1250 kilowatt hours of electricity in September. She pays the same amount for every kilowatt hour of

electricity

Which function C(k) models the amount Liana will pay for using k kilowatt hours of electricity in one month

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i.e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
