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?1. 20 bottles of soda at $1.50 each2. 4 six-packs of soda at $5.00 each3. one case of 24 sodas at $18.504. two cases of 24 sodas at $18.50 each

3. one case of 24 sodas @ $ 18.50

Explanation:

The question requires that the hosts need to have enough to have two sodas each. The number of guests being 10, the requirement is to have 20 sodas.

Now comparing the various pack sizes available:

1. 20 sodas $ 1.50 per bottle, Total cost $ 30, per serving cost $1.50

2. 4 6 packs @ $ 5 each. Total cost $20, Per serving cost $0.83

3. 24 soda case @ $18.5. Total cost $ 18.50, Per Serving costs $ 0.77

4, 2 x 24 soda cases @ 18.50. Total Cost $ 37.00 Per serving costs $ 0.77

The per serving costs are the same in 3 & 4 above, however, since the requirement is to have 20 sodas and the overall costs as well as the per serving costs is the best in option 3, this is the preferred option.
