All you have to do is to convert the cost per hour to the cost per unit once at the beginning, and you don’t havetoworry about conversion after that.For problems 1 to 7, the conversion has been done for you below:•Convert cost per hour to cost per unit: (Regular-time labor cost per hour)(labor standard per unit) = (regular-timelaborcost per unit)= 126 = $72. This is the cost of regular production.•(Overtime labor cost per hour) × (labor standard per unit) = (overtime laborcost per unit) =166 = $96. This is thecost of overtime production.•Convert“time available” to “production rate”:(regular time available per period) / (labor standard per unit) = 160/6= 26.67. This is the regular production rate per worker per period.
