Give the step-by-step reasoning process and then the final answer. John builds a toy bridge to support various weights. It needs to support 6 cans of soda that have 12 ounces of soda. The cans weigh 2 ounces empty. He then also adds 2 more empty cans. How much weight must the bridge hold up?
The weight of soda was 6 * 12 = 72 ounces. It had to support the weight of 6 + 2 = 8 empty cans. The weight of the empty cans is 8 * 2 = 16 ounces. So it must support 72 + 16 = 88 ounces.
The final answer: 88.
