An investor opened an account with an online brokerage firm and deposited $1,000.00 into the account. she then used all the money in the account to buy some shares in a company, costing her $15.00 in fees, and made a 10% profit on the remainder of her money. she then sold the shares, costing her $15.00 in fees, and bought some shares in another company with the remainder of her money, costing her $15.00 in fees, and she made a 10% profit on the remainder of her money. finally, she sold the shares, costing her $15.00 in fees. which of these recursive formulas will produce the sequence that represents her original number of dollars, her number of dollars after her first sale, and her number of dollars after her second sale?

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.)
