To do this, we will need to find how much the elevator can hold in all. Multiply 10 by 250 to get 2500. Since it can also hold 10% more, multiply 2500 and 0.10 to find out how much 10% is. You get 250. Add 2500 and 250 to get how much the elevator can safely hold. It would be 2750.

To find out how much more weight can be added, first find out how much weight is on the elevator collectively. (books) 600 + (Jim) 180 + (Gavin) 330 + (Deb) 250 + (Susan) 120 = 1480. Subtract this from the amount the elevator can hold, and you get how much more weight can be added. 2750-1480 = 1270.

The elevator can hold 1270 more ibs.

It can still hold another 268 pounds. If you add the weight of everyone and everything it is 2680. They say it can still hold another 10% (move the decimal twice left) which means you just have to multiply 2680 by. 10 to find the percentage more. That should be equal to 268.
