The monthly cost of downloading songs at b-Tunes is $0.99 per song. I-Music charges a
monthly fee of $10 plus an additional $0.79 per song. How many songs would you have to
download for the two plans to cost the same?

Answer:

50

Step-by-step explanation:

0.99x = 10 + 0.79x

0.2x = 10

x = 10/0.2 = 50

Step-by-step explanation:

[tex]bcost = 0.99 \times x[/tex]

[tex]icost = 0.79 \times x + 10[/tex]

x is the amout of songs downloaded

if this is for one month only, there is no need for a variable with the $10

set them equal to each other

[tex]0.99 \times x = 0.79 \times x + 10[/tex]

solve for x

[tex]0.2 \times x = 10 \\ x = 50[/tex]

so you'll need to download 50 songs for these plans to cost the same
