Money is invested in two accounts, twice as much in one paying 3% interest per year as in the other, which pays 4% interest per year. The total interest earned after one year is $140. If x is the amount invested at the 3% rate
and the y is the amount invested at the 4% rate, then write a system of equations that will have a solution that
gives the amount invested at each rate, and find the x and y?
