A data plan includes 15 GB per month. After 8 GB used, there are 7 days left in the month. What is the maximum average daily usage allowed to not exceed the cap?

Explanation:
Think about spreading the remaining data evenly over the days left. After using 8 GB, you have 7 GB left. There are 7 days remaining, so to avoid exceeding the 15 GB cap you can use at most 7 GB across 7 days, which is 1 GB per day on average. If you average more than that, you’d go over the limit; if you average less, you’d stay under the cap. So the maximum average daily usage is 1 GB per day.
