Question

An online music service lets customers download an unlimited number of songs for $0.25 each after paying a monthly membership fee of $5.00. If $10.25 was billed to the customer, how many songs were downloaded that month?

Answer 1

In this case, 21 songs were downloaded.

Step-by-step explanation:

To calculate the number of songs downloaded in a month, we need to subtract the fixed monthly membership fee from the total amount billed and then divide the remaining amount by the cost per song.

Let's define some variables:

M = Monthly membership fee = $5.00

C = Cost per song = $0.25

B = Total amount billed = $10.25

To find the number of songs downloaded, we can use the following equation:

Number of songs downloaded = (B - M) / C

Substituting the values:

Number of songs downloaded = ($10.25 - $5.00) / $0.25

= 21

Therefore, 21 songs were downloaded that month.
