The cost of going to a movie theater increases annually. If it costs $7.83, with tax, to go to the movie theater in 2020, the function f (x) = 7.83(1.04) can be used to determine how much it will cost to go to the movie theater 2 years after 2020, where = 1 represents going to the movie theater during 2021.
Which best represents the domain of the function in this context?
all rational numbers
O all real numbers
O negative integers only
nonnegative integers only

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.)
