In a game show, Lauren starts out with 500 points. For getting Question 1 right, she gets an additional x points for a total of (500 + x) points. For getting Question 2 right, her score is multiplied by y for a total of y(500 + x) points.
If she gets Question 3 right, making her final score 1,000y^2 + 2xy^2, by what value was her score multiplied for getting the third question right?
A
2
B
2y
C
2y^2
D
2 + y
E
2 + x

y * (500 + x) = 500y + xy
(1000y^2 + 2xy^2) / (500y + xy) = 2y
(1000y^2 + 2xy^2) / (500y + xy) = 2y

A=2.
