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:
[tex]3m+4n=79[/tex]
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":
[tex]3m+4n=79\\3m+4(11+m)=79\\3m+44+4m=79\\7m+44=79\\7m=35\\m=5[/tex]
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
