Answer:
x = 25
Step-by-step explanation:
2/5x - 1 = 9
Add 1 to both sides
2/5x = 10
Multiply both sides by the reciprocal of 2/5, which would be 5/2
x = 25

Derivatives problem! I love these!
To maximize revenue: Find where R(p) has a maximum
1. Find the derivative
-4p^2 + 2000p - 3000
= (2)(-4p) + (1)2000 - (0)3000
= -8p + 2000
2. Find where the derivative = 0
-8p + 2000 = 0
2000 = 8p
250 = p
<u>a. Price = 250</u>
3. Plug in p to your original equation
-4(250)^2 + 2000(250) - 3000
= 247,000
<u>b. Maximum revenue: $247,000</u>
