Susie Q has 1000 dollars to invest. She invests some of the money at the Pretty Penny Bank, which compounds annually at 3 percent. She invests the rest of the money at the Five and Dime Bank, which compounds annually at 5 percent. After two years, Susie has a total of $\$1090.02$. How much did Susie Q originally invest at the Pretty Penny Bank, in dollars?

p = penny bank amount

1000 - p = f & d bank amount

 

p ( 1 + .03)2    + (1000-p) ( 1 + .05)2   = 1090.02               can you solve this for p ?
