To find the total mass of the 10 adults, we need to convert their masses from kilograms to pounds. One kilogram is equal to 2.20462 pounds, so the mass of one adult in pounds is:
80 kilograms * 2.20462 pounds/kilogram = 176 pounds
The total mass of the 10 adults would be:
10 adults * 176 pounds/adult = 1760 pounds
Since the elevador can hold at most 2,500 pounds, we can see that the elevador can carry the 10 adults without exceeding its weight limit. The elevador would have a remaining weight capacity of:
2,500 pounds - 1,760 pounds = 740 pounds.
