Lincoln Cantrell · Answer 1

Website A:

c = 10 + 0.25 s

where c is the cost and s is the number of songs.

Website B:

c = 0.75 s

The equation (answer):

10 + 0.25 s = 0.75 s

We can solve this equation:

10 = 0.5 s

s = 10 : 0.5

s = 20 (Marvin would have to buy 20 songs to to make the costs equal)
