Ming Wing invested $10,000, part at 4% and part at 5% simple interest for a period of 1 year. How much was invested in each account if the interest earned in the 5% account was $320 greater than the interest earned in the 4% account?

OK Katie. You need to create 2 equations to solve for your two unknowns. Equation 1: 2 accounts <<--- pick any two variables to represent the 5% and 4% interest accounts. Together the principle invested in the two accounts adds up to what?
Never-mind. I see you worked with cantoset in the chat room.
