Problems on a Test

n g
10 40
18 72
21 84

The table shows the grade, g, on a test when the number of problems, n, are correct. Write an equation to model this situation.
A) g = 4n
B) n = 4g
C) g = n + 30
D) n = g - 30

Answer 1

G = 4n is the correct equation to use. Eg 10 x 4 = 40, 18 x 4 = 72 and 21 x 4 = 84
