Answer:

Explanation:

(a) R(x) = x(150 - 0.75x) => 150x - 0.75x²

(b) P(x) = R(x) - C(x) => 150x - 0.75x² - (2000 + 0.75x²)

so, P(x) = 150x - 2000 - 1.5x²

(c) Now, P '(x) = 150 - 3x = 0....at maximum

i.e. when x = 50 suits

(d) P(50) = 150(50) - 2000 - 1.5(50)²

=> 7500 - 2000 - 3750

i.e. £1750

(e) price --> 150 - 0.75(50) => 150 - 37.5

Hence, price per suit is £112.50 in order to maximise profits.
