Answer:
or approximately (0.544, 4.179)
Step-by-step explanation:
A function and its tangent lines intersect when their slopes are the same. Find the x-coordinate when the slope of f(x) is equal to 8/7 by taking the derivative of f(x):
Set 
equal to 8/7 and solve for x:
Therefore, 
will intersect at a point of tangency with a line of slope 8/7 at x=49/900. Plug in x=49/900 into to get the y-coordinate:
⇒Answer: (49/900, 3761/900) or approximately (0.544, 4.179)

The profit function is the difference between the cost and revenue functions
The profit function is 
<h3>How to calculate the profit function</h3>
The functions are given as:
- Cost function: C(x) =0.6x + 15000
- Revenue function: R(x) =1.25x
The profit function is then calculated as:
So, we have:
Evaluate the differences
Hence, the profit function is
