Question

If a standard vodka martini recipe at La-ti-da Lounge calls for 2.5 oz of premium vodka that sells for $35/liter, .5 oz of dry vermouth that sells for $7.99 a liter, and one jumbo gourmet olive for 15 cents, and the martini sells for $15, what is the drink cost percentage?
a. 19.3 percent
b. 14.7 percent
c. 12.5 percent
d. 16.5 percent

Answer 1

Answer: (A) 19.3%

Step-by-step explanation:

$\text{Vodka: }2.5\text{ oz }\times\dfrac{\ 35}{1\text{ liter }}\times\dfrac{1\text{ liter }}{33.814\text{ oz }}=\ 2.59\\\\\text{Vermouth: }0.5\text{ oz }\times\dfrac{\ 7.99}{1\text{ liter }}\times\dfrac{1\text{ liter }}{33.814\text{ oz }}=\ 0.12\\\\\text{Olive: }\ 0.15$

Vodka + Vermouth + Olive = Total Cost

$2.59  +   $0.12      + $0.15 = $2.86

$\dfrac{\text{cost to make}}{\text{selling price}} = \dfrac{\ 2.86}{\ 15} = 0.19 = 19\%$
