The minimum price that the barber must charge <em>to increase his salary to $4,000</em> for each of the 200 haircuts is <em>A. $25.</em>
Data and Calculations:
Charge per haircut = $20
Total cost per month = $4,000
Monthly salary = $3,000
Other costs per month = $1,000 ($4,000 - $3,000)
Minimum number of haircuts per month = 200
Expected monthly salary per month = $4,000
Total new monthly expenses = $5,000
Minimum price to charge per haircut = $25 ($5,000/200)
Thus, the minimum price that the barber must charge <em>to increase his salary to $4,000</em> without increasing the number of haircuts is $25.
