Answer:
233.98 kg or 233 kg and 980 g
Explanation:
First, I'd convert all the units to be the same and write out all the values that are given.
1 packet = 9 kg 340g = 9.34 kg
box = 480 g = .48 kg
Since you have 25 packets, you have to add 9.34 to itself 25 times, or multiply it by 25.
total packet weight = 9.34 kg x 25
= 233.5 kg
Then, add together all the packets and the box.
Total weight = 233.5 kg + 0.48 kg
= 233.98 kg
or 233 kg and 980 g
I hope this helps!
