Going from the top of the right side down it would be: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
Answer:
{(0, 0), (1, 2), (2, 4), (3, 4)
Step-by-step explanation:
the x in the ordered pair is not suppose to repeat, clearly this doesn't
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 )
