Question

A formula for 8 bottles of window cleaner calls for 6 cups of rubbing alcohol, 2.25 gallons of water, and 1.5 cups of ammonia. How many quarts of rubbing alcohol would the formula call for if a factory made 1,280 bottles for stores to sell to customers?

Answer 1

Answer:

240 quarts

Step-by-step explanation:

If 8 bottles of window cleaner calls for 6 cups of rubbing alcohol and we want to know how many quarts of rubbing alcohol would the formula call for 1,280 bottles, the next proportion must be satisfied:

8/1280 = 6/x

x = 6*1280/8

x = 960 cups

We know that 1 cup =  0.25 quarts, then, the conversion of cup to quart is:

960*0.25 = 240 quarts

Answer 2

240 quarts----------
