Cool Tees is having a Back to School sale where all t-shirts are discounted by 15%. Joshua wants to buy
five shirts: one costs $9.99, two cost $11.99 each, and two others cost $21.00 each.
a. What is the total cost of the shirts including the discount? b. By law, sales tax is calculated on the discounted price of the shirts. Would the total cost of the shirts
including the 6.5% sales tax be greater if the tax was applied before a 15% discount is taken, rather
than after a 15% discount is taken? Explain. c. Joshua remembered he had a coupon in his pocket that would take an additional 30% off the price
of the shirts. Calculate the new total cost of the shirts including the sales tax.
d.
If the price of each shirt is 120% of the wholesale price, write an equation and find the wholesale
price for a $21 shirt.

If angle 2=3x +1 and angle 3=2x +4what is angle 2

Solve the equation. 2x - 8(x+1)= 6(2x - 3)

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.)
