A cabinet maker used 0.75 gallons of varnish on 10 cabinet doors. At this rate, how many quarts of varnish are required for 25 cabinet doors?

  7.5 quarts

Step-by-step explanation:

There are 4 quarts in a gallon, so 0.75 gallons is 3 quarts. Varnish is being used at the rate of ...

  (3 quarts)/(10 doors) = 0.3 quarts/door

At that rate, the amount required for 25 doors is ...

  (0.3 quarts/door)(25 doors) = 7.5 quarts

7.5 quarts are required for 25 doors.

since both sides equal, there are infinitely many olutions.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
