Question

A formula for 8 bottles of window cleaner calls for 6 cups of rubbing alcohol, 2 1/4 gallons of water, and 1 1/2

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

1 quart = 4 cups

since 6 cups ( 6/4=1.5 quarts) are used for 8 bottles

than 1280/8 = 160

160*1.5 = 240 quarts are needed
