You can put this solution on YOUR website!
Let x = overall grade (in decimal form)


The final is worth 200/1000 = 20% of your overall grade. Everything else is 100 - 20 = 80% of your grade


80% of other stuff + 20% of final = overall grade

0.80*0.75 + 0.20*0.78 = x

0.756 = x

x = 0.756

0.756 = 0.756*(100%) = 75.6%


Your overall grade is 75.6%
