Please answer the following question by reasoning step-by-step.
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?

36000
First Store:50000(.

10) = 5000.

50000 - 5000 = 45000 pounds.

Second Store:45000(.

20) = 9000.

45000 - 9000 = 36000 pounds.

.

Therefore, the answer is 36000
