Kelly has twice as many CDs as Lou. Tiffany has three times as many CDs as Lou. Altogether they have 372 CDs. How many more CDs does Tiffany have than Lou?

x = # Lou's CDs, then 2x = Kelly's and 3x = Tiffany's.

x + 2x + 3x = 372

Solve for x.

3x - x = ?

x+0

2x+93
3x+186

To find out how many more CDs Tiffany has than Lou, we first need to determine the number of CDs each person has.

Let's assume Lou has x number of CDs.

Kelly has twice as many CDs as Lou, so Kelly has 2x CDs.

Tiffany has three times as many CDs as Lou, so Tiffany has 3x CDs.

According to the given information, the total number of CDs the three people have is 372:

x + 2x + 3x = 372
6x = 372
x = 62

Now that we know Lou has 62 CDs, we can calculate the number of CDs each person has:

Lou: 62 CDs
Kelly: 2 * 62 = 124 CDs
Tiffany: 3 * 62 = 186 CDs

To find out how many more CDs Tiffany has than Lou, we subtract their CD counts:

Tiffany - Lou = 186 - 62 = 124

Therefore, Tiffany has 124 more CDs than Lou.
