Answer:
Shelly used 16 gigabytes of storage.
Explanation:
To find the total storage, we need to divide the amount of used storage by the percentage used.
First, we need to convert the percentage to a decimal by dividing by 100: 93% = 0.93
Then, we divide the used storage by the decimal conversion of the percentage: 15 gigabytes / 0.93 = 16.1290322581 gigabytes
So, the total storage is approximately 16.13 gigabytes.
