the sanitation department calculated that last year each city resident produced approximately 1.643 × 10^3 pounds of garbage. there are 2.61 × 10^5 people living in the city. how much garbage did the city sanitation department collect last year?
4.2882 pounds
428.820 pounds
428,820 pounds
428,820,000 pounds

428,820,000 pounds

Step-by-step explanation:

The amount of garbage is number of person times the amount produced by each person. Thus, we have:

Amount of Garbage (in pounds) = 2.61 × 10^5 * 1.643 × 10^3

Note: We multiply 2.61 and 1.643, which is 4.28823 & multiplying 10^5 and 10^3 is 10^(5+3) = 10^8

Thus, we have 4.28823 * 10^8 = 428,823,000 pounds

This is approximately 428,820,000 pounds, last answer choice.
