Select the set of equations that represents the following situation: Mike invested $199 for one year. He invested part of it at 5% and the rest at 7%. At the end of the year he earned $10.75 in interest. How much did Mike invest at each rate of interest? x + y = 199; 0.05x + 0.07y = 10.75 0.05x + 0.07y = 199; x + y = 10.75 0.05 · 199 + 0.07 · 199 = 10.75 x + y = 199; 5x + 7y = 10.75
