Kara found two websites that she could use to download songs.
The first website charges a one-time membership fee of $5 and $0.99 per song.
The second website has a one-time membership fee of $10. In addition, the second website charges $0.89 per song.
Which equation could be used to determine how many downloaded songs, d, must be purchased for the cost at the two websites to be the same?
A. 5d + 0.99 = 10d + 0.89
A. , 5d + 0.99 = 10d + 0.89
B. 5+ 0.89d = 10 + 0.99d
B. , 5+ 0.89d = 10 + 0.99d
C. 5 + 0.99d = 10 + 0.89d
C. , 5 + 0.99d = 10 + 0.89d
D. 5d + 0.89 = 10d + 0.99
