Use the substitution method from using the mutiple choices.

The two numbers must equal to each other.

x= 2

(2+50)/2= 13(2)

add first then divide

(52)/2= 13(2)

26= 26

Answer: x= 2

(x+50)/2 = 13x

First multiply both sides by 2 to remove the fraction:

x +50 = 26x

Subtract 1x from each side:

50 = 25x

Divide both sides by 25:

x = 50/25

x = 2

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

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