Select the set of equations that represents the following situation: Mike invested $706 for one year. He invested part of it at 5% and the rest at 3%. At the end of the year he earned $28.00 in interest. How much did Mike invest at each rate of interest?
0.05x + 0.03y = 706; x + y = 28.00, x + y = 706; 5x + 3y = 28.00, 0.05 • 706 + 0.03 • 706 = 28.00, x + y = 706; 0.05x + 0.03y = 28.00
