Manuel bought pounds of apples and eat 3/4 of 1 pound
That is 0.75 pounds
Thus 9-0.75=8.25 pounds of apples left with him.
It is given that the cost of 25 pounds of Apple is dollar.
Let the cost of 1 pound of Apple be x.
8.25 multiply X=15
8.25x. 10
————. = ——
8.25. 8.25
X=10
——
8.25
X=1.818181
X=2
Then the cost of Apple is above two dollars per pound
