Lizzy: Cilia wants to buy a multi-level dumbbell system. The first pair of dumbbells are 3 lb weights, the second pair is 5 lb weights and the third is 8 lb pounds. How much does the entire system weigh?.
Me: Hmmm, let me think. I think this is the detailed solution:
The first pair of weights weighs 3 lb each so all total they weigh 2 * 3 = 6 lbs. The second pair of weights weigh 5 lbs each so they weigh 2 * 5 = 10 lbs. The third pair of weights weigh 8 lbs each so they weigh 2 * 8 = 16lbs. All total, the entire system of weights weigh 6 + 10 + 16 = 32 lbs. Final answer: 32.
