Abbott Manufacturing produces plastic cases for solar photovoltaic panels and has decided to combine orders from customers to increase work order size, and thereby make one large production run per model type. Plastic injection molding machines are used to make these parts, and it is time consuming to clean the machines and set them up again between production runs. Each molding machine and operator works one 9-hour shift with a one-hour lunch break and one-half hour for operator breaks. What is the total workload (demand) in hours for this work order mix? Round your answer to one decimal place. The total workload is hours. How many machines are needed to do this work in 1, 2, or 3 days? Round your answers up to the nearest whole number. To do this work in 1 day they need machine(s). To do this work in 2 days they need machine(s). To do this work in 3 days they need machine(s)
