How many one-gallon cans of lubricating oil should be ordered if a facility uses 600 quarts of oil each month?

  1. 100 cans

  2. 150 cans

  3. 200 cans

  4. 250 cans

The correct answer is: 150 cans

To determine the correct number of one-gallon cans of lubricating oil required for a facility that uses 600 quarts of oil each month, it’s crucial to first convert quarts to gallons, since the cans being ordered are measured in gallons. There are 4 quarts in one gallon. To find out how many gallons of oil are needed for the facility, divide the total quarts used per month by the number of quarts in a gallon: 600 quarts ÷ 4 quarts/gallon = 150 gallons Since each can holds one gallon, the facility will therefore need to order 150 cans of lubricating oil to meet its monthly usage. This calculation confirms that the proper order quantity aligns clearly with the facility's monthly oil consumption.
