How many pounds does the right supply tank hold?

• A. 104
• B. 1530
• C. 1308
• D. 118

Answer: (D)

When you’re figuring how much the right supply tank holds, the key is to use the weights shown for that tank and apply the arithmetic indicated by the diagram. If the diagram gives the empty weight of the tank and the weight of its contents, you add those quantities to get the total pounds the tank holds. If instead you’re given a combined total for both tanks and the weight of the other tank, you subtract that other amount from the total to isolate the right tank’s weight. Following the numbers in this setup leads to 118 pounds for the right tank. This value accounts for all components shown (tank itself plus contents) and aligns with the data given.
