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?
To find the number of songs that Marvin would have to buy each month to make the costs of the music websites equal, you can set up the equation:
Cost of using Website A = Cost of using Website B
The cost of using Website A can be calculated as the sum of the subscription fee and the cost of the songs:
10 + 0.25s
The cost of using Website B can be calculated as the cost of the songs (since there is no subscription fee):
0.75s
So the equation to solve would be:
10 + 0.25s = 0.75s
To find the equation, we need to compare the costs of both websites and set them equal to each other. The total cost of using Website A would be the sum of the subscription fee ($10) and the cost per song ($0.25 * s, where s represents the number of songs Marvin buys). For Website B, the total cost would be the cost per song multiplied by the number of songs (0.75s).
So, the equation to find the number of songs Marvin would have to buy each month to make the costs of the music websites equal is:
10 + 0.25s = 0.75s
10 + .25x = .75x
Solve for x.
