The weight, w, in tons of a school bus is related linearly to its seating capacity, p. A 60-passenger bus weighs 10 tons, and an 84-passenger school bus weighs 13 tons. Which equation can be used to find the weight of a 50-passenger bus? (PLS explain!!)
1. w-10=50/71(50-60)
2. w-10 = 71/50(50-60)
3. w-10 = 8(50-60)
4. w-10 = 1/8(50-60)
