Answer :
Final answer:
After accounting for the weight of the elevator operator, the elevator at a construction site can safely lift 32 bags of cement in a single trip.
Explanation:
The scenario provided involves calculating the maximum number of cement bags that a construction elevator can hold, considering both the weight of the cement and the operator. First, we need to subtract the elevator operator's weight from the elevator's maximum capacity. This would give us 1515 - 235 = 1280 pounds. This is the weight capacity left for the cement bags.
Next, we would need to determine how many cement bags can be lifted safely by dividing the remaining weight by the weight of each bag. Doing this calculation 1280 / 40 results in 32 (ignoring any decimal since we cannot have part of a bag). Therefore, 32 bags of cement can be lifted in one trip alongside the operator.
