continuation problem

and another question

PROBLEMS 1. Given the following data, compute the production standard (pieces per hour), the standard labor cost per 100 pieces, and the standard hours per 100 pieces. The allowances are 4% for fatigue, 8% for unavoidable delays, and 8% for personal needs. The operator is paid $5.00 per hour. Performance rating = 105%. (Instructor: Look also at Problem 12.)
