Factory A produced 392,850 cans.
Factory B produced 25,000 fewer cans.
We can write that out as:
392,850 - 25,000 cans
Which equals:
367,850 cans
Factory B sold some tins and had 12,400 cans left.
To figure out how many cans Factory B sold, we can subtract how many they had left from their original amount.
We can write that out as:
367,850 - 12,400 cans
Which equals:
355,450 cans
Factory B sold 80 cans more than Factory A.
To figure out how many cans Factory A sold, we can subtract how many more Factory A sold than them.
We can write that out as:
355,450 - 80 cans
Which equals:
355,370 cans
So, Factory A sold 355,370 cans, and Factory B sold 355,450 cans.
