1 answer

To find the weight of the dump truck when 15,300 pounds of trash is added, we need to add the weights together.

Empty dump truck weight: 2.8×10^5 pounds
Trash weight: 1.53×10^4 pounds

Adding these two weights together gives us:
2.8×10^5 + 1.53×10^4 = 3.95×10^5 pounds

Therefore, the weight of the dump truck when 15,300 pounds of trash is added is 3.95×10^5 pounds.
