PLEASE HELP ME The systems of equations models the profits of two home- based internet companies. P=-1200+2.5N
P=-5000+1.6N
The variable P represents profit in dollars, and N represents his to the company's website
A. Use the substitution method to find an exact solution.
B. Is an approximate or exact solution more meaningful in this model?

Given:

solve:

A.

Find P:

B.

As the number continues and is endless, it is an approximate solution.

A)

B) approximate

Step-by-step explanation:

A) Substitute into and solve for N:

To find P, substitute found value of N into one of the equations and solve for P:

B) An approximate solution is more meaningful as hits to a website are measured in whole numbers not rationals or decimals.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
