About my work and grade

Question

if i have a 78.93% and i have a assignment thats worth 50% of my grade how far will it drop if i get a low grade or 0 on it. 

Answer 1

If your 78.93 is the other 50% and you don't do the assignment, you have the same amount of points but it's the entire 100%, so your grade would divide in half and you'd have a 39.47.
