Answer:
In the end he would have made a total of 234 dollars
Step-by-step explanation:
440-128=312 This is the amount left after taking out the rotten apples
312/4= 78 Since he then put the apples in groups of four, he would have 78 groups of four apples a piece.
78 X 3= 234 Lastly he would have a profit of 234 dollars seeing as he has 78 groups of apples, each individual group costing 3 dollars a piece
