Question 1 of 8
select the correct answer.
darlene places $500 in a savings account that pays 4% interest. the amount, t years after 2005, can be modeled by the following
equation.
g(t) = 500(1.04)
elisa places $600 in a savings account that pays 5% interest. the amount, t years after 2005, can be modeled by the following table.
1t05 10 15 20
f(t) $600 $766 5977 $1,24751,592
based on these values, which account has the greater average rate of change between 2005 and 2015?
o

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.)
