Answer:
Yes
Explanation:
According to USA labor law an employee who is under 20 years of age might be paid a rate of $4.25 per hour for his/ her 90 days of work.
According to above condition
Number of hour worked by employee = 40 hours
Rate of pay = $170 / 40 = $4.25 per hour
As this is his first job and 90 hours limit is not exceeded yet, his Employer paid him correctly.
