This isn't done by an equation. Start dividing 100 / 7. Since this won't give you an integer, round the result up. Now multiply this result by 7, to get a multiple of 7. Add 7 to the result, then add 7 again, and again, until you get over 200.

What is the equation to figure out what grade you need on a final?
You first need to know how much the final contributes to the total grade. Let that be X%, so the final contributes X/100 to the semester grade, and your work, so far, contributes (1 - X/100).If G is your average before the final, and F is the grade earned on the final, and T is the total grade:T = G*(1-X/100) + F*(X/100). Rearranging, we get:F =(T-(1-X/100)*G)/(X/100)So if the final is worth 25%, {X/100 = 0.25}, and you have an 89, now, substituting in, you would need a 93 on the final to get a 90 for the class.If the final is worth 25%, and you have an 95, now, you would need a 75 on the final to get a 90 for the class.
