How many hours overtime did a man work if he was paid $168?
A man's regular pay is $3 per hour up to 40 hours. Overtime is twice the payment for regular time.

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
