A company's marginal profits were determined to be given by the function: 23 -x + 4 1 P'(x) = 4 with P' is measured in thousands of dollars per unit. When the company doubled their production output, from b units to 2b units, their profits increased by a net change of 7 thousand dollars. Find the value of b, knowing that it is a whole number greater than 0.
