Daily Number of Hours Worked by Karen / Total Numbers of Work Units Completed 1/100 2/190 3/270 4/340 5/400 6/450 7/480 8/500 Karen's total cost to the firm is $11 per hour. Each work unit completed is worth $0.21 to the firm. Ignoring all other possibilities and considerations, for how many hours should the firm hire Karen per day

Answer 1
