Joe has a term mark of 68%. If his term work is worth 70%
So he has 0.68*70 = 47.6 points
-------------------------
and his exam is worth 30%, what percent does he need on the exam to increase his mark to 70%
----
Equation:
Points + Points = 70
x*30 + 47.6= 70
30x = 22.4
x = 0.7466 = 0.75 when rounded up
