Answer 1

To find the total weight of the dump truck after adding the trash, we add the weight of the empty dump truck (2.8×105 pounds) and the weight of the trash (15,300 pounds).

2.8×105 pounds + 15,300 pounds = 2.8153×105 pounds

Thus, the weight of the dump truck after adding the trash is 2.8153×105 pounds, which can be written in scientific notation as 2.8153 times 10 superscript 5 pounds.
