Cost for 3 gas tanks. 2) What facts does the problem give? Gas is \$3 a gallon.  His 3 gas tanks hold 2 gallons each. 3) Are there any word clues in the problem? 4) What do I need to do to get the answer? First you need to find out how many total gallons of gas Johnny is buying. Since he has 3 tanks, and they each hold 2 gallons, you can either add (2+2+2) or multiply (3x2) to get 6 gallons.  To find out how much the 6 gallons will cost, you will multiply: 6 x \$3 = \$18.  Johnny will spend \$18 to fill up all of the gas tanks.
