I have 57% in my math class, My final is worth 15%. If My mark goes 51% or below I fail the class. What % will I need to get on the test to pass it?
+36915 SO your 57% is worth 85%
57(85%) + x(.15) >= 51 Where x is the score you will need on your final to keep you grade above 51% overall
solve for x
48.45 + .15 x >= 51
.15x>2.55
x > = 17 THAT is a pretty low bar...I hope you will aim MUCH higher than THAT !
