The price of a stock, A (x), over a 12-month period decreased and then increased

according to the equation A (x) = 0.75x^2 - 6x + 20, where x represents the number of

months. The price of another stock, B (x), increased according to the equation

B (x) = 2.75x + 1.50 over the same 12 month period.

Solve the system of equations algebraically to figure out all prices, to the nearest

cent, when both stock prices are the same.

A) $13.49 and $22.86

OB) $11.27 and $23.88

C) $14.27 and $20.07

D) $9.13 and $25.96
