Re: Francisco’s MP3 player with a capacity of 64 gigabytes (GB)

Explanation
If Francisco’s MP3 player is three-quarters full, the current content equals \(\frac{3}{4} \times 64\) GB = 48 GB.
He then deleted 25%, or 12 GB, of that data, reducing the amount of data saved to 48 – 12 = 36 GB.
After saving 20 GB of new data to the device, it holds 36 + 20 = 56 GB. This is \(\frac{56}{64} \times 100 = 87.5%\) of the total capacity.
