Answer:
Explanation:
Step 1. Given information.
- City of 200 people
- 100 rich, 100 poor.
Step 2. Formulas needed to solve the exercise.
- P(poor) = 0.9x^2
- P(rich)= 35x-0.1x^2
Step 3. Calculation and step 4. Solution.
P(poor) = p (rich)
0.9x2 = 35x - 0.1x2
1x2 = 35x
x = 35
x is the percentage of rich above 50%, thus there are 35% rich people above 50%.
P (poor) = 1102.5
P (rich) = 1102.5
The equilibrium premium is $1,102.5
