Question

It costs $0.25 to download an individual song and $2 to download an album. Whitney has $9 to spend downloading music.

Complete the table showing three ways Whitney can spend $9 downloading individual songs and albums.

Answer 1

Explanation:

The number of dollars Left always needs to be even if you want to buy albums last because we can never have half an album. So if you download 4 songs that leaves you left with $8.

0.25x4

=1

Now with the rest of the money you can download 4 albums.

4 individual songs, 4 albums.

0.25x4+4x2

=1+8

= $9

12 individual songs, 3 albums

0.25x12+2x3

= 3+6

=$9

20 individual song, 2 albums

0.25x20+ 2x2

= 5+4

= $9
