Suppose that you invest $17600.00 between two accounts. The first account is safer and yields 5.8% interest. The second account is riskier, but yields an interest rate of 9.8%. Letting x denote the amount of money invested in the first, safer account, and letting y denote the amount of money invested in the second, riskier account, setup a system of linear equations which you could solve to find out how much money you should invest in the accounts so that you earn $1380.80 in interest per year.
Equation 1:
Equation 2:
