We make sample calculations per month, assuming that you visit the gym x times per month.
(1) $39.95 per month
(2) total = $14.95 + $2.95x
If we have the value of x, it is much easier for us to determine the answer by just substituting the value of x and solve. Whichever gives the lower cost will be our answer.
Answer:
Option A. 56
Step-by-step explanation:
The question talks about chosing 5 presenters out of 8 presenter.
This can be achieved b using the following formula:
nCr = n! /r! (n–r)!
n = 8
r = 5
8C5 = 8! / 5! (8 – 5)!
8C5 = 8! / 5! 3!
8C5 = (8 x 7 x 6) / (3 x 2 x 1)
8C5 = 56
Therefore, there are 56 ways in which the teacher can chose the presenters.
6 x 10 = 60
divide 60 by 3
your answer is 20 :)
Hope that made sence

I think it is R but then again this is still a guess
