aWhile studying for the engineering economy final

exam, you and two friends find yourselves craving a

fresh pizza. You can't spare the time to pick up the pizza

and must have it delivered. "Pick-Up-Sticks" offers a

1-1/4-inch-thick (including toppings), 20-inch square

pizza with your choice of two toppings for $15 plus 5%

sales tax and a $1.50 delivery charge (no sales tax on

delivery charge). "Fred's" offers the round, deep-dish

Sasquatch, which is 20 inches in diameter. It is 1-3/4

inches thick, includes two toppings, and costs $17.25

plus 5% sales tax and free delivery.

a. What is the problem in this situation? Please state it

in an explicit and precise manner.

b. Systematically apply the seven principles of

engineering economy (pp. 3-6) to the problem you

have defined in Part (a).

c. Assuming that your common unit of measure is

dollars (i.e., cost), what is the better value for getting

a pizza based on the criterion of minimizing cost per

unit of volume?

d. What other criteria might be used to select which

pizza to purchase?
