Answer to Question #314007 in Financial Math for tododekusimp

Question

Aaron’s cell-phone plan includes 3GB of data. On the 21st day of his billing period, Aaron received a message from his service provider that he has already used 75% of his data allowance for the 31-day billing period. At this rate, will he use more than 3GB of data for the month?

Answer 1

On the 21st day of Aaron's billing period, he had already spent 75% of 3gb = 2.25gb. So his data balance at this time was 3gb-2.25gb=0.75gb

Now we will determine his daily data usage

2.25/21=0.1071gb

So everyday Aaron spends 0.1071gb

In the remaining 10 days, Aaron will spend 0.1071gb*10=1.071gb

Since he is left with 0.75gb of data while his schedule shows that he requires 1.071gb of data, then he will require extra data more than the 3gb
