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

let x = amount of $invested at 10% then (3000-x) = amount of$ invested at 8%

(.10)x + (.08)(3000-x) = 256
