Final answer:
The best way to estimate the combined weight of the people in the elevator when the total weight is 49% of the 3025-pound capacity is to find 50% of 4000 pounds. Option 4 is the correct choice.
Step-by-step explanation:
To estimate the combined weight of the people in the elevator, we need to find 49% of the 3025-pound capacity.
Option 3: Find 50% of 3000. This is not the best option because it assumes the capacity is 3000 pounds, which is not the exact value.
Option 4: Find 50% of 4000. This is the best option because it assumes the capacity is 4000 pounds, which is closer to the actual capacity. Therefore, the correct option is Option 4.
