Question 1049406: (1 point) Suppose that you invest $16200.00 between two accounts. The first account is safer and yields 4 percent interest. The second account is riskier, but yields an interest rate of 8.9 percent. 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 $1010.60 in interest per year.
Equation 1:
Equation 2:

(1 point) Suppose that you invest $16200.00 between two accounts. The first account is safer and yields 4 percent interest.
The second account is riskier, but yields an interest rate of 8.9 percent. 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 $1010.60 in interest per year.
Equation 1: x + y = 16200.
Equation 2: 0.04x + 0.089y = 1010.6
Isn't it absolutely obvious?
