To find out how many rock CDs Gisela has, we need to gather the given information and solve the problem step by step.
We know that Gisela has a total of 135 CDs. Out of these, 11 are pop music CDs. Let's represent the number of rock CDs she has as "x."
Given that she has three times as many rock CDs as classical CDs, we can set up the equation: 3 * (number of classical CDs) = number of rock CDs.
We need to find the number of rock CDs, so let's find the number of classical CDs first. We know that she has 135 CDs in total, and 11 of them are pop music CDs. So the number of classical CDs can be found by subtracting the number of pop music CDs from the total: (135 - 11) = 124.
Now, we can substitute the number of classical CDs into the equation and solve for the number of rock CDs:
3 * (number of classical CDs) = number of rock CDs
3 * 124 = x
Multiplying 3 by 124 gives us 372.
Therefore, Gisela has 372 rock CDs.
