Think about what you've been actually doing when you calculate the average of two numbers, let's say 80 and 60. If you add them and divide by 2, you get 70. What you're really doing is saying that each number contributes 50% (or 0.5) of the total:
80 x 0.5 = 40
60 x 0.5 = 30
40 + 30 = 70!
So in your problem, you just need to multiply each number by its worth and add up the products.

If the exam is worth 10%, everything else is worth 90%. So 90% of your grade is the 96 you already have .9*96. The exam is worth 10% of your grade, so if you get a 60 that would be .1*60. Think of it this way: 90% of your grade is a 96, 10% is a 60, that is represented by (.9*96)+(.1*60) = 92.4% total in the class.
