Answer:
Profit = $6
Step-by-step explanation:
The box of apple that the man bought contained 100 apples.
These 100 apples were gotten for $44
Then he sold the 100 apples for $0.5 each.
So sales price = 0.5 * 100 = $50
To know if he made profit or loss.
Sales price - cost price
$50 - $44
= $6
This man made profit of $6 from the sales of the apples from the calculation above.
