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?
How many pounds are unloaded at the first store? ** First Store:50000(.10)=<<5000=5000>>5000
How many pounds are left after the first store? ** 50000-5000=<<50000-5000=45000>>45000 pounds
How many pounds are unloaded at the second store? ** Second Store:45000(.20)=9000
How many pounds are left after the second store? ** 45000-9000=<<45000-9000=36000>>36000 pounds
