Slope-Intercept Applications ( = mx +O)

Afina-wow [57]

The cost of downloading the app and downloading 30 songs is $40.7

Step-by-step explanation:

The equation can be written using slope-intercept form

Let x be the number of songs

Then

$1.29 per song will be written as

1.29x

for x number of songs

The initial charges are $2 so the equation will be:

$f(x) = 1.29x+2$

To find the cost of 30 songs, we have to put x= 30

So,

$= 1.29(30)+2\\=38.7+2\\=40.7$

Hence,

The cost of downloading the app and downloading 30 songs is $40.7
