Question

The function g(t) = 2t represents the number of guitar lessons, g(t), you can complete in t months. How many guitar lessons can you complete in 7 months?

Answer 1

substitute the value of t in the given function

Answer 2

is t 7

Answer 3

It is not 7.

Answer 4

g(t) just means that if you put in a value for t, you get g(t). You could just as easily call it m, so m = 2t.
They tell you that you can complete "2t" lessons in 1 month, how many can you complete in 7 months?
What if I told you that you could have 3 lessons in a month, after 8 months how many lessons would you have taken?

Answer 5

24

Answer 6

Correct, now apply that same logic to the question at hand, if you can do 2t lessons in a month, how many lessons can you do in t=7 months?

Answer 7

In your second response you asked, "is t 7", I said it is not, but when I read it I though you said, "is it 7".. I apologize for leading you astray. In fact, 't' IS 7 in this problem.

Answer 8

lol it's cool so its 2(7)=14 lessons

Answer 9

You got it. :)
