Answer:

65.54% (nearest hundredth)

Step-by-step explanation:

Given:

$\sf \mu=9000$

$\sf \sigma=1000$

$\sf X \sim N(\mu, \sigma^2)\implies X \sim N(9000,1000^2)$

P(X > 8600) = 1 - P(X ≤ 8600)

= 1 - 0.3445782584

= 0.6554217416

= 65.54%

You need work your cost into your total profit, $75, which was spent. Since that money was lost, we can say it is -$75. You make 50¢ per cup of hot choclate, which is $0.50. Putting that all together, you can make the function P = .50c - 75.
