Answer:

Step-by-step explanation:
The given rational expression is:

We can use concept of Partial Fractions to solve this problem. Let,

Multiplying both sides by (x - 1)(x - 5), we get:

Substituting x = 5, we get:

Substituting x = 1, we get:

Substituting the value of A and B, back in the original equation, we get:

Vertex formula = -b/2a
-18/1 = 18.
However, this is just the x value, the vertex is (x,y)
-18*2 + 18(18) - 72 = 576
A) (18,576)
576 dollars made with 18 members is the highest amount made in one day.
B) (12,0) (6,0)
$102,105-$100,000= $2105
$2105/10 =$210.5
1000*.07*.5= $3500
3500- 210.5 = $3289.5
So in my estimation, it is $3,318.41
