Brainliest is waiting to be given to the correct 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:

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":

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

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
