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.
Let us assume that the course has x hours per week. Then A should have attended 10x hours in 10 weeks. Actually he has only taken part at 70% of 10 x h, that means he has taken part at 7x hours.
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%.
