A college student earned $5100 during a summer vacation working as a waiter at a popular restaraunt. The student invested part of the money at 9% and the rest at 8%. If the student recieved a total of $445 in interest at the end of the year, how much was invested at 9%?

Question

I think you divide 0.09 into $445. Since they are only wanting how much of it was invested at 9%, I think that the 8% part would be unnecessary or extra information.
