The absolute decrease was of 33 million.

The relative decrease was of 22.45%.

Step-by-step explanation:

Absolute change

The absolute change is the number of CD's sold is the number of CD's sold in 2010 subtracted by the numbers of CD's sold in 2009.

The number is negative, which means that there was a decrease.

114 million - 147 million = - 33 million

The absolute decrease was of 33 million.

Relative change

The relative change is the absolute change divided by the initial value.

So - 33/147 = - 0.2245

Which means that the relative decrease was of 22.45%.
