Answer:
To calculate how much Keller makes, you can follow these steps:
1. Find Keller's share of the total market:
Keller's share = 22% of 1.25 million people
Keller's share = 0.22 * 1,250,000
Keller's share = 275,000 people
2. Calculate Keller's earnings:
Earnings per head = $2.50
Total earnings = Earnings per head * Keller's share
Total earnings = $2.50 * 275,000
Now, calculate the total earnings:
Total earnings = $687,500
So, Keller makes $687,500 from his market share.
