7+7=14. You can draw pictures, count on your hands, etc.

The formula for a rotation 270° counterclockwise about the origin is (x,y)--->(y,-x)
D'(4,2) E'(7,-4) F'(3,-10) G'(0,-8)
Booster's share =y =0.75x
gross receipts=x=700
plug x=700 in y=0.75x
y=0.75*700
y=525
Her horizontal distance to the rim satisfies the ratio
(10 ft -6 ft)/distance = tan(25°)
so the distance is
distance = (4 ft)/tan(25°) ≈ 9 ft
