Call the amount invested in stocks, x, and the amount invested in bonds, 9000-x

 

So we have

 

.05x  +  (9000-x).08  =   525    simplify

 

.05x  + 720 - .08x  = 525

 

.03x  + 720  = 525     subtract 720 from both sides

 

-.03x  = -195   divide both sides by .03

 

x = $6500  = amt in stocks

9000 - x  = 9000 - 6500  = $2500  = amt in bonds

 

 

cool cool cool
