Let K be the number of songs on Kelly's music player,
L be the number of songs on Lou's music player and T be the number of songs on Tiffany's music player.
We know that,
K = 4*L
and
T = 6*L
and also
K + T + L = 682
Then,
4*L + 6*L + L = 682
11L = 682
L = 62
From here we know that
T = 6*62 = 372
K = 4*62 = 248
So Kelly has 248 songs on her music player

Answer:
3/8 * 24 = 72/8 = 9
5/9 * 18 = 90/9 = 10
11/12 * 36 = 396/12 = 33
Answer:
The answer to your question is the letter A.20%
Step-by-step explanation:
Data
Questions correct in the first attempt = 25
Questions correct in the second attempt = 30
Percent of increase = ?
Process
1.- Use proportions and cross multiplication to solve this problem. 25 questions is 100%.
25 questions -------------------- 100%
30 questions -------------------- x
x = (30 x 100)/25
x = 3000/25
x = 120 %
2.- Subtract 100 from 120%
Percent increase = 120 - 100
= 20%
