The boxes of Oranges can be represented by x.

The boxes of grapefruit can be represented by y.

If he made 8,125 dollars, then he made it off of 10 and 11 dollar boxes.

So, 11x+10y=8,125

And if he sold 762 boxes, they could only be orange and grapefruit boxes.

So, x+y=762

So we can solve for y.

y=762-x

Then we substitute.

11x+10(762-x)=8,125

And solve for x.

x+7,620=8,125

x=505

So, there were 505 boxes of oranges.
