Total mark = secondyearmark * 0.25 + thirdyearmark * 0.75
60 = 55(0.25) + x(0.75)
Solve for x
Hi,
I'm at university, I wanted to find a formula that would calculate what average I need to achieve for the rest of the year.
At our university we do 120 credits every year. The second year is worth 25% of the total mark, the third year is worth 75%.
So, say (for example) I got an average of 55% in my second year. How would I work out what I needed to average in my final year to attain an overall average of 60%?
I know this might look simple to you - but I haven't studied maths for the last 8 years and I just can't fugure it out!
