Answer:

There is 7.5% increase in the number of songs on his mp3 player.

Step-by-step explanation:

Original Songs in mp3= 440 songs

Final Songs in mp3= 473 songs

We need to find percent of increase in the number of songs on his mp3 player.

The formula used is: Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100

Now putting values and finding percent of increase

Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100\\Percent \ of \ increase = \frac{473-440}{440} \times 100\\Percent \ of \ increase = 7.5\%

So, there is 7.5% increase in the number of songs on his mp3 player.
