Application
Sophie plans to invest 18,000,000w, putting
part of the money x into a savings that pays
5% annually and the rest into an account
that pays 8% annually.
What are the possible values of x.
If she wants to invests x dollars at 5%, write
an equation that describes the total interest I
received from both accounts at the end of the
year.
How much must she invest at 5% to earn
1,020,000w in one year?
