Dark Beer is purchased by the case for 18.90

Question

There are 24 bottles in each case, and each bottle contains 12 fl oz. You are making brine that requires 2 1/2 quarts of dark beer. How much will the beer cost for brine? 

Answer 1

Juliet, 24(12) = 288 fl. oz. cost $18.90. One quart is 32 oz., so 2 1/2 quarts is 80 oz.

 

18.9/288 = x/80

288x = 18.9(80)

288x = 1512

x = 5.25

 

The beer for the brine will cost $5.25.
