Question 599426: Select the set of equations that represents the following situation: Mary invested one amount at 1% simple interest, and a second amount at 6% interest, earning $17.68 in one year. If she had switched the amounts, she would have earned $14.04. What were the two amounts

0.01x + 0.06y = 14.04; 0.01x + 0.06y = 17.68
0.01x + 0.06y = 17.68; 0.01y + 0.06x = 14.04
x + 6y = 17.68; y + 6x = 14.04
x + 6y = 14.04; x + 6y = 17.68
