Answer:

$C.\frac{1}{6}$

Step-by-step explanation:

First in order to calculate this you just have to solve the multiplication of the signs:

-(-1/2)= 1/2

So what you will actually do would be add 1/2 to -1/3, as you know you have to move the point in the line, the line is advancing at 1/6 at a time so -1/3 would be -2/6 so you need to move to the left from 1/2 two stops, and you will end up in 1/6 and that would be the answer.

If a club charges dues of $200 a year, it will have 50 members. For each $5 it raises its dues, it loses a member. USE AN EQUATI

Vikentia [17]

Answer:

The value is $y = \$ 225$

Step-by-step explanation:

From the question we are told that

The amount charge per year is $k = \$ 200$

The number of members it will have at this amount is $n = 50$

The amount amount increase that will lead to the loss of a single member is $z = \$ 5$

Generally the total amount the club would obtain from its members is mathematically represented as

$I = Amount \ due\ paid * Number \ of members$

Now let x denote the number of member lost

Hence

$I = (k + zx) (n-x )$

=> $I = (200 + 5x) (50-x )$

=> $I = 10000+50x-5x^2$

Thus the number of members that be removed to give the maximum income from dues is obtained by differentiating the above equation and equating it to zero

$\frac{dI}{dx} = 50-10x$
