if i currently have a 65% in a class and my final is worth 20% of my grade, what do i need to get on my final in order to have a 60% at the end of the class? What do I need to get on my final in order to have a 50%. Thank you

Answer:

60%= 40

50%=not possible

Step-by-step explanation:

x=grade on final

(65*.8) + (x*.2)=60

52+.2x=60

.2x=8

x=40

(65*.8) + (x*.2)=50

52+.2x=50

.2x=-2

x=-10

not possible
