The amount of data left on a cell phone plan is 6 GB after eight days 1.5 GB of data is use each day how much that is available at the beginning of the cycle

18GB was present at the beginning of the cycle

Step-by-step explanation:

We are asked to calculate the amount of data initially available at the beginning of a circle given that what is left now is 6GB and 1.5GB have been used daily for the past 8 days.

To calculate the amount of data initially present, what we do is to simply add what is left now plus what has been used.

We know what is left now which is 6GB. What we are to calculate is what had been used. To know what had been used, we simply multiply the number of days by 1.5GB

This is same as 1.5 * 8 = 12GB

The initial amount of data present is thus 12GB + 6GB = 18GB
