How would i figure out what my mark is if I have a 92%, but then got a 57% on a project worth 10%?
Your mark is 92% of everything you have so far, which is only 90% of your overall mark. That means of the 10% project, you have a further 57%.
To find the final mark, you are work with the two marks together to get a total out of 100:
`92(0.90)+57(0.10)` multiply then add
`=82.8+5.7` now add
The new percentage is 88.5%
