Mr. and mrs. atoll are planning a party for 10 people and want to make sure they have enough soda for everyone to have two bottles. which of the following makes the most economic sense?
a. 20 bottles of soda at $1.50 each
b. 4 six-packs of soda at $5.00 each
c. one case of 24 sodas at $18.50
d. two cases of 24 sodas at $18.50 each

C. One case of 24 sodas at $18.50

Explanation:

The key is in the unit cost per bottle.

A. Each bottle of soda costs $1.50

B. 6 bottles sodas at $5.00 = $5.00/6 bottles = $ 0.83 per bottle

C. This options represent the lowest cost for each bottle of soda. If We divide $18.50 by 24 the unit cost is $0.77 per bottle.

Besides, 24 bottles is an enough amount for the guests, guaranteeing at least two bottles per guest as Mr. and Mrs. Atoll want.

D. Although the unit cost is the same as option C, the amount exceeds what is really needed for the party. This option involves incurring unnecessary expense.
