Bruce went to Taco Villa twice last week. On his first visit he bought 1 bean burritos and a 2 tacos for $8.90. On his second visit he bought 4 bean burritos and 3 tacos for $10.00 more than his first visit. The price of each bean burrito and the price of each taco is the same each visit. Write a system of equations that can be used to find the price
of each bean burrito, b, and the price of each taco, t?

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.)
