A. 1.50c+ 4.00a = 5050 (Money earned)

Neither of them are correct. When you plug in both of the fractions into the equation, you get answers like 2/9 (from plugging in 1/3) and 1/9 (from plugging in 1/6). None of them are equal to 9.
X^2-9=0 add 9 to both sides
x^2=9 take the square root of both sides
x=±3
