Can someone please help me : You wish to invest $90,000 in two accounts. You want a very aggressive investment strategy, so you intend to invest in an account with a rate of 11.8% and another with a rate of 22.3%. With this strategy, at the end of one year, you want to earn $16,668.00. How much should you invest in each account?
System of linear equations
Let money in one account be 'x' and money in other account be 'y' This gives you your first equation, x + y = 90000. This goes to: y = 90000 - x Let the interest rate of account where you invest 'x' be 11.8%. The return on this account will by 1.118x Let the interest rate of account where you invest 'y' be 22.3%. The return on this account will be 1.223y This gives you your second equation, 1.118x + 1.223y = 106668 Put y = 90000 -x in equation above. That will give you x= 32400, and hence y=57600
