Question

An online Media Service offers Video and music downloads. Each download of a song costs $1.25. Each download of a video costs 4 times as much as the song download. You have a credit of $70. How many songs can you purchase after buying 12 videos

Answer 1

8

Explanation:

First, you need to find the cost of one video. We know that the cost of 1 video is equal to 4 times the cost of each song. So we will take the cost of a song $1.25 and multiply by four.

$1.25(4) = $5

So if one video costs $5, we now need to find the cost of 12 videos because we need to know how many songs you can purchase after you purchase 12 videos.

12($5) = $60

Now that we know that you have spent $60 on your videos, we need to figure out how many songs you can purchase now that we know you have $10 remaining of the initial $70. To do this, we will divide $10 by $1.25

$10/$1.25 = 8

With $70, given that you have already purchased 12 videos, you can also purchase 8 songs.
