If it is 
=2c+9, go to AAAAAA
if it is (
)(4c+16)=2c+9, go to BBBBB
AAAAAAAAA
=2c+9
=2c+9
times 4c+16 to both sides
1=(2c+9)(4c+16)
distribute
1=8c^2+68c+144
minus 1 both sides
0=8c^2+68c+143
use quadratic formula
c=
or 
BBBBBBBBBBBB
(3/3)(4c+16)=2c+9
1(4c+16)=2c+9
4c+16=2c+9
minus 2c both sides
2c+16=9
minus 16 both sides
2c=-7
divide both sides by 2
c=-7/2
c=-3.5
if it is=2c+9,

The profit function is the difference between the cost and revenue functions
The profit function is
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
