Question 1119239: I am also stuck on this interest problem, I tried working it out with a system of equations which gave me a repeating decimal.
"Egbert invested $2,500 at 10% interest for one year. He has an additional $6,000 to deposit. At what rate must he invest the $6,000 to end the year with a total balance of exactly $9,440?"
Thank you!

r, the needed interest rate as a percent. (yearly rate)

2500%2A%281%2B10%2F100%29%2B6000%2A%281%2Br%2F100%29=9440
