Let the Number of Songs in the Music Player of Lou be : L
Given that Kelly has 4 times as many songs as Lou has in her Music Player
⇒ The Number of songs in Music Player of Kelly = 4 × L
Given that Tiffany has 6 times as many songs as Lou has in her Music Player
⇒ The Number of songs in Music Player of Tiffany = 6 × L
Given that Altogether have 682 songs in their Music Players
⇒ Tiffany songs + Lou songs + Kelly songs = 682
⇒ 6L + L + 4L = 682
⇒ 11L = 682
⇒ L = 62
⇒ Number of Songs in Music Player of Lou = 62
⇒ Number of Songs in Music Player of Kelly = 4 × L = 4 × 62 = 248
Answer:
$3.19
Step-by-step explanation:
so he starts with $18.90 and we know that he spent $2.95. So we will subtract $2.95 from $18.90. So we are left with $15.95. But now its says he bought 5 items with $15.95. So we will divide 15.95 by 5. So the price of the item that he bought 5 of is $3.19
If you are at a higher level you can use this method:
make and equation of: 5x + 2.95 = 18.90
with this you would subtract 2.95 and then divide by 5 just like we did above.
