Answer 2

Answer: Bentley have to pay $20.5 in a month in which he downloaded 10 songs.

Bentley have to pay $(13+0.75s) in a month in which he downloaded s songs.

Explanation:

As per given,

Total amount need to pay = (Monthly cost) + (Number of songs downloads) x (Charges for each song)

Here, Monthly cost = $13

Charges for each song = $0.75

If Number of songs downloads = 10

Then, Total amount need to pay = $ (13 +(10) (0.75))

= $( 13+7.5)

= $ 20.5

So, Bentley have to pay $20.5 in a month in which he downloaded 10 songs.

If Number of songs downloads = s

Then, Total amount need to pay (in $) = 13 + (s)(0.75)

= 13+0.75s

So, Bentley have to pay $(13+0.75s) in a month in which he downloaded s songs.
