The average of 7 numbers is x. What does 14x represent?

Question

Please help! I have the SAT tomorrow!

Answer 1

Mark is correct.  Look at what x represents:

 

x = (a+b+c+d+e+f+g)/7

 

14x = 14[(a+b+c+d+e+f+g)/7]

x = 2(a+b+c+d+e+f+g)

 

So x is 2(sum of the 7 #'s)

Answer 2

Twice the sum of the 7 numbers.
