Question

My grade is a 77%, if i get a 0% on a paper worth 30% of my grade, what will my grade be now??

Answer 1

`Grade=Paper+Other`

`Grade=(Grade_(paper)* Value_(paper))+(Grade_(other)* Value_(other))`

`Grade=(0 * 30\%)+(77\% * (1-30\%))`

`Grade=(0 * 30\%)+(77\% * 70\%)`

`Grade=0+53.9\%`

`Grade=53.9\%`
