We break this question into two parts; the first 10 hours, which totals $100 for 10 hours, and the next few hours at $8 per hour.

We then proceed to find out whether Bruce used more than 10 hours of Internet or not. From there, we work out Bruce’s excess time spent on the Internet by using the $8 rate and then calculate the number of hours of Internet used in total.

Finally, we used the fact that Bruce used the Internet for 3 hours daily to find the duration of Bruce’s stay.
