Hi Georgia, I think the question should read If you invest 500$, some at a 7% annum and the balance at a 10% annum and your interest earned is 44$annum how much was invested in the 7% and how much in the 10%. Let$d\$$be the amount you invest at 7% then the amount you invest at 10% is 500\ - d\. After one year the d\$$ has earned $0.07 \times d\$$interest. How much interest do you earn from the investment at 10%? The total interest earned is$44\$.$ Solve for d.
