Answer:
300 kg
Step-by-step explanation:
Thinking process:
You need to know the conversion:
1 hectogram = 0.1 kg
Therefore, 7000 hectograms gives:
![7000 (0.1) = 700 kg](https://tex.z-dn.net/?f=7000%20%280.1%29%20%20%3D%20700%20kg)
The elevator can take a maximum of 1 000kg.
The reminder is ![1000 - 700\\= 300 kg](https://tex.z-dn.net/?f=1000%20-%20700%5C%5C%3D%20300%20kg)
The elevator will take 300 kg more
