Question

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

Answer 1

What relationship do you see here, between the tables n and g?

Answer 2

addition

Answer 3

Well, it must be common between each layer.

Answer 4

g=n+30

Answer 5

Try input 18 for n, does it work?

Answer 6

I don't know what you mean

Answer 7

For n it has 18, what is the subsequent g value?

Answer 8

72

Answer 9

So would g= n + 30 work?

Answer 10

72 = 18 + 30
72 = 48

72 does not equal 48

Answer 11

So g=n+30 would not work for this entire set of data. Only the first set of values.

Answer 12

I'm confused

Answer 13

Me 24/7 :D

Answer 14

It's A. Input any n value into g = 4n and you will get the appropriate g value.

Answer 15
