Marvin is comparing two different music websites. Website A charges $10 per month for a subscription and $0.25 per song. Website
B has no subscription fee, and all songs cost $0.75. Which equation would you solve to find the number of songs, s, that Marvin would have to buy each month to make the costs of the music websites equal?
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 )
