Given:-
Ms. Boyrer is writing a program to compute ad costs. She needs to enter an algebraic
representation of the costs of a local paper's ad. The charge is $32.25 for up to three
lines for a classified ad. Each additional line costs $6.
To find:-
Express the cost of an ad f(x) with x lines as a function of x algebraically.
So now the algebraic equation is,
So these is the required expression.
We have
and
so the equation is indeed exact. So we want to find a function such that
Integrating both sides of the first equation wrt gives
Differentiating both sides wrt gives
So we have
or
Answer:
When 4864 books are sold
Step-by-step explanation:
Create an equation where x is the number of books produced:
The first method will be represented by 10.75x + 82,910
The second method will be represented by 23.25x + 22,110
Set these equal to each other and solve for x:
10.75x + 82,910 = 23.25x + 22,110
82,910 = 12.5x + 22,110
60,800 = 12.5x
4864 = x
So, the costs will be the same for both methods when 4864 books are sold
Answer: 85
Step-by-step explanation:
I = prt
I = .035(50)(20)
I = 35
35 + 50 = 85
sorry if wrong but i think its the answer
