Answer:
18 dollars
Step-by-step explanation:
Marginal cost can be defined as the additional cost to produce every additional unit of a certain good. In mathematical terms;
Marginal cost = change in cost / change in quantity
For seven jackets, we have to find the difference between the cost of seven jackets and the cost of six jackets as follows
$101 - $83 = $18
Since the change in quantity is one, our marginal cost comes to $18.
84 divided by 2 is 48
one set of 48-12 is 36
36 students are in the science club
Given:
The function is
The binomial 
is a factor of f(x).
To find:
The value of 
.
Solution:
If 
is a factor of f(x), then 
.
It is given that, is a factor of f(x), then 
.
We have,
Substituting x=4, we get
Now,
Therefore, the value of a is 5.
