Question 1204128

Let number of shares at $2.00  be x
And  number of shares at $3,25   be y

The investor bought 300 shares of stock, 

So, x+y = 300.....................................................(1)

Investment 
 the total cost was $756.25,

2x+3.25y = 756.25..............................................(2)

Now x+y = 300 multiply by 2

2x+2y = 600
2x+3.25y = 756.25   Subtract the equations ( From (2)

-1.25y = -156.25

divide by -1.25

y = -156.25/ -1.25
y =125

x = 300-125= 175

So, the investor bought 175 shares at $2.00 per share and 125 shares at $3.25 per share.


CHECK
175*2+3.25*125 =756.25
