Question

A certain elevator has a maximum weight capacity of 1,000 kilograms. Ten people weighing a total of 7,000 hectograms get on the elevator. How much more weight can the elevator hold before it reaches its maximum capacity?

Answer 1

7000 hectograms = 700 kilograms, as 1 hectogram = 0.1 kilograms

if the total weight capacity is 1000kg, then
1000-700 = 300
and therefore the elevator can hold 300kg more before it reaches its maximum capacity
