Comprehensive and Detailed in-Depth Explanation:
Under the Fair Labor Standards Act (FLSA), deductions for uniforms cannot reduce an employee's wages below the federal minimum wage. As of 2025, the federal minimum wage is $7.25 per hour. For 30 hours of work, the minimum wage earnings would be 30 hours × $7.25/hour = $217.50. The employee's actual earnings are 30 hours × $7.75/hour = $232.50. The difference between actual earnings and minimum wage earnings is $15.00. Therefore, the maximum allowable uniform deduction is $15.00. However, since the proposed deduction is $45.00, which exceeds the allowable amount, the employer cannot deduct the $45.00 without violating the minimum wage requirement. Therefore, the correct answer is A. $0.00.
