Answer:
Step-by-step explanation:
<u>Given function:</u>
<h3>Part A</h3>
<u>p(d) = 2300, find d:</u>
- 2300 = -5d² + 300d - 200
- 5d² - 300d + 200 - 2300 = 0
- 5d² - 300d - 2100 = 0
- d² - 60d - 420 = 0
- d²- 2*30d + 900 = 1320
- (d - 30)² = 1320
- d- 30 = √1320
- d = 30 + 36.33
- d = 66.33
<h3>Part B</h3>
<u>Maximum point of the function is obtained at vertex, which is (x = -b/2a):</u>
<u>The maximum profit is:</u>
- p(30) = -5(30)² + 300(30) - 200 = 4300
