The correct answer to this question is option A – 8
If a man's regular pay is $3 per hour for up to 40 hours of work, this means he makes $120 for 40 hours. When he works overtime, he makes double per hour ($3 x2).
If he was paid $168 for all hours work (regular pay + overtime pay), we could easily tell how many hours he worked overtime.
Regular pay = $3 per hour for 40 hours = $120
Total amount earned = $168
The amount earned from overtime work = 168 – 120
Since the man gets double per for overtime, we have to divide his overtime earning by overtime hourly rate
Overtime hours worked = 48/($3x2)
Therefore, the man worked 8 hours of overtime to be paid a total of $168.
The correct answer to this question is A, 8. To find this answer, one should know first multiple the pay times the number of regular hours. This would create the equation 3 x 40, which equals 120. From there, you would subtract this amount from the full amount earned. That establishes the equation 168 - 120. This gives us 48.
Then, we need to divide this amount by the hourly wage, which provides the equation with 48 / 3= 16. Being that overtime is double, we would need to use division again, this time dividing 16 /2, which gives us our answer of 8.
At $3 per hour up to 40 hours, regular pay = $3 x 40 = $120 If total pay = $168, overtime pay = $168 - $120 = $48 Overtime rate (twice regular) = 2 x $3 = $6 per hour ; hence number of overtime hours = $48/$6 = 8
