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.
He now attends the remaining 2x hours and at the end of the course he has attended 7x + 2x = 9x hours of 12x possible hours. That's a percentage of 75%.
