Answer:
$1.87 per guest for quantity used
$1.91 per guest for whole bottles used
$3.06 per guest for whole cases used
Step-by-step explanation:
The cost of the beverage is ...
($189.43/case)(1 case/(12 bottles))(1 bottle/(750 mL)) = $0.02104777.../mL
Each guest consumes 6 cocktails of 0.5 floz each, so ...
(6 drinks/gues)(0.5 floz/drink)(29.5735295625 mL/floz) ≈ 88.7205 mL/guest
Then the cost per guest is ...
($0.02104777.../mL)(88.7205 mL/guest) ≈ $1.86737/guest
The cost per guest for the amount used is about $1.87.
__
The total amount of drink used for all guests is ...
124(88.7205 mL/guest) ≈ 11,001.4 mL
At 750 mL per bottle, this is ...
(11,001.4 mL)/(750 mL/bottle) ≈ 14.7 bottles
If you're constrained to pay for 15 bottles, then the cost per guest is ...
$189.43(15/12)/124 = $1.91 per guest
__
At 12 bottles per case, this is ...
(14.7 bottles)/(12 bottles/case) ≈ 1.2 cases
If you're constrained to pay for 2 cases, then the cost per guest is ...
$189.43(2)/124 = $3.06 per guest
