Professional painters were hired to repaint the inside of several rooms in a building. Each room is exactly the same size. The painters use 3.36 gallons to complete 4.20 rooms. How many gallons of paint are used to paint one room? A. 0.80 gallons B. 0.84 gallons C. 1.25 gallons D. 7.56 gallons

Respuesta :

The number of gallons of paint used to cover the insides of the wall of the room is calculated by dividing the number of gallons used for 4.2 rooms. 

This is as follows,

                   n = 3.36 gallons / 4.2 rooms

Simplifying,

                   n = 0.8 gallon/room

The answer to this item is A.
