Hi there,
400 apples at $20 each = $8000
Sold 360 for $8600
Then $8600 - $8000 = $600
Your gain is $600
Hope this helps :-)
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
you bought 400 apples at 20 dollars each.
your cost is 400 * 20 = 8000 dollars.
you sold 360 apples for 8600 dollars.

your gain is 8600 - 8000 = 600 dollars.

you only needed to know the number of apples to determine the the total cost.

it was 400 * 20 = 8000.

you did not need to know the number of apples sold because you are told that the total revenue that you got back was 8600.

your total gain is equal to total revenue minus total cost which is equal to 8600 minus 8000 which is equal to 600.

if want to know the net gain per apple sold versus net gain per apple bought, then the numbers become important.

your net gain per apple sold is 600/360.

your net gain per apple bought is 600/400.
