Here, for the solution, r is equal to 275x, c is equal to 75x plus 11 ,000.
00:11
Now for the part a, p is equal to r minus c, so p will be equal to by substituting the values, we get 275x minus 75x minus 11 ,000, which is equal to p is equal to 200x minus 11 ,000.
00:28
This is the answer for the part a.
00:32
Now, for the part b, p is equal to 200 x minus 11 ,000.
00:39
Here it is given that x is equal to 2000.
00:42
So we substitute the value of x in the next step.
00:46
We get p is equal to 200 multiply by 2000 minus 11 ,000...
