To find the weight of the dump truck after adding the trash, we need to add the weight of the trash to the weight of the empty dump truck.
Weight of empty dump truck: 2.8×10^5 pounds
Weight of trash added: 15,300 pounds
To add these values, we can simply add the numerical values and keep the same exponent:
2.8×10^5 + 15,300 = 2.8×10^5 + 1.53×10^4 = 2.953×10^5 pounds
Therefore, the weight of the dump truck after adding the trash is 2.953×10^5 pounds.
The answer is d. 2.953×10^5 pounds.
