Select the set of equations that represents the following situation: Mary invested one amount at 8% simple interest, and a second amount at 5% interest, earning $49.16 in one year. If she had switched the amounts, she would have earned $52.37. What were the two amounts?
(Points : 3)
8x + 5y = 49.16; 8y + 5x = 52.37
0.08x + 0.05y = 49.16; 0.08y + 0.05x = 52.37
8x + 5y = 52.37; 8x + 5y = 49.16
0.08x + 0.05y = 52.37; 0.08x + 0.05y = 49.16

8x+5y=52.37;8x+5y=49.16

anonymous · Answer

noh
it sud be
0.08 x + 0.05 y = $ 49.16
0.08 y  + 0.05 x = 52.37
