An 8-ounce cup of gourmet coffee costs $4.50. If the unit price remains the same, how much would 3 quarts of coffee cost?

Answers

Since there are 32 fluid ounces in 1 quart and we need 3 quarts we multiply 32 and 3 and get the result of which is 96 we need to divide that by eight to get the correct number to multiply 4.50 by so we get the result of 12 now it is 12 times 4.50 which is 54 so it costs 54 dollars. I hope this was helpful. 
1 quart = 32 fl oz. 
This means that if there are 3 quarts, and each quart contains 32 ounces, 3 quarts have 96 ounces. 
3 quarts * 32 oz = 96 oz 

Now, set up a proportion. 
8 oz is to $4.50 as 96 oz is to "x" 

8 oz = $4.50 
96 oz = x 

Cross multiply to solve. 

4.50 * 96 = 8x 
432 = 8x 
Divide both sides by 8: 
x = 54

3 quarts of coffee would cost $54. 
This doesn't make sense in a real life situation, but I'm confident that it is correct.
