Pat invested a total of $3,000. Part of the money yields 10 percent interest per year, and the rest yields 8 percent interest per year. If the total yearly interest from this investment is $256, how much did Pat invest at 10 percent and how much at 8 percent?

• let one amount be x and other 3000-x
  then we get an eqn. 8/100(x)+10/100(3000-x)=256
  solving this we get x=2200 and the remaining amount is 3000-2200=800
