I need a little help with the following problem.
Student A is attending a study course for 12 weeks in total.
He has just finished 10 of the 12 weeks.
His attendance after 10 weeks is at 70%.
If he goes to all his classes for the remaining 2 weeks, what will his attendance be at the end of the course?
I'm unsure how to calculate this.
Thanks!
Punky.
