Q: A tractor trailer has a load of 50000 pounds. 10% of the weight gets unloaded at the first store, and 20% of the remaining load is removed at the second store. How much weight, in pounds, is left on the truck after the two deliveries?
A: First Store:50000(.10) = 5000. 50000 - 5000 = 45000 pounds. Second Store:45000(.20) = 9000. 45000 - 9000 = 36000 pounds. The answer is 36000.

Question: There are 3 rows of people relaxing at the beach. The first row is made up of 24 people until 3 people get up to wade in the water. 5 people from the second row, which originally held 20 people, go to join them.
