Question

Select the set of equations that represents the following situation: Mary invested one amount at 5% simple interest, and a second amount at 4% interest, earning $21.32 in one year. If she had switched the amounts, she would have earned $25.84. What were the two amounts?

0.05x + 0.04y = 25.84; 0.05x + 0.04y = 21.32
5x + 4y = 21.32; 5y + 4x = 25.84
0.05x + 0.04y = 21.32; 0.05y + 0.04x = 25.84
5x + 4y = 25.84; 5x + 4y = 21.32
