Question

your friends know you enjoy music, so they buy you a gift card for $20.00 to a popular online music provider. Each download costs $1.39. What is the balance on the gift card if you download as many songs as without going over the gift card limit?

Answer 1

$0.54

Explanation:

Cost of each song is $1.39

He has a gift card of $20 from which he can buy songs .

So, number of songs he can buy from the gift card =
`(20)/(1.39)`

= 14.388

So, he can buy 14 songs from the gift card

Cost of 1 song = $1.39

So, cost of 14 songs =
`1.39* 14`

=
`19.46`

So, he can spend $19.46 to buy as many songs without going over the gift card limit

So, balance on gift card =
`20-19.46`

=
`0.54`

Hence ,The balance on the gift card if you download as many songs as without going over the gift card limit is $0.54

Answer 2

The answer would be 54 cents, or 0.54. Here's proof;

If a song costs 1.39, and you want to blow all of the money you got on a ton of songs, you would divide $20 by 1.39 to find out how many songs you can buy. Then you take that number, and times it by 1.39 to see the exact cost of those songs. You can then take the cost, and subtract it from your balance to get your answer.

20/1.39 = 14.38(because you can't go over your limit, you round to the nearest whole number, 14)

14 x $1.39 = $19.46

$20.00 - $19.46 = $0.54.

Hope this helped!
