Most of Conservative Casey's money was put into a savings account that paid 5% interest a year, but some of it was put into a risky stock fund that paid 16% a year. Casey's total initial investment in the two accounts was $10000. At     the  end   of   the   first   year,   Casey   received a total of $775 in interest from the two accounts. Find the amount invested in each.

x = money at 5% interest

10000 -x    = money at 16%

 

.05 x  +  .16 ( 10000 - x ) = 775

x = 7500 at 5%        then 2500 at 16 %
