Answer 1

Answer:

D

Step-by-step explanation:

Let cost of member be "m" and cost of non-member be "n".

We know:

3 member and 4 non-member pay $79.

So we can say:

$3m+4n=79$

Also, from the problem, we know that:

non-member fee is 11 more than member fee

Thus, we can write:

n = 11 + m

Putting this in 1st equation, we can solve for "m":

$3m+4n=79\\3m+4(11+m)=79\\3m+44+4m=79\\7m+44=79\\7m=35\\m=5$

Members have to pay $5, so non-members will pay "11" more, that will be:

Non-Members = 11 + 5 = 16

$16, D is the correct answer
