IF I get this grade on my final what grade will I get in the class?
Hey guys I wwas wondering If anyone was good at figuring these out.
Marine Science: I have a 76 in the class, and I want an 80. If the final is 10 percent of the grade, what percent do I need to get an 80?
Theology: I have a 77 and I want an 80 in the class. If the final is is 20 percent of the grade, what percent do I need to get an 80?

ummm im not 100% sure that i did it correctly for you first class you would have to get a 116% on the final =/ and in your other class i got that you would have to get at least a 92%
what i did to get those was ---- where x is = the grade you need to get on final (incase someone whats to see if i did it the right way
(.9)(76) + .1x = 80
68.4 + .1x = 80
.1x = 11.6
x = 116
and for the second one:
(.8)(77) + .2x= 80
61.6+.2x = 80
.2x = 18.4
x = 92
anyways good luck with your finals!

116 because 76(90%) + x(.1) = 80
