I would like help with this problem.

2. You work as an operations manager at the Fisher-Price toys company. Fisher-Price employees are currently working a total Fisher Price in of 12 hours per day to produce 240 dolls. You think that by changing the paint used for the facial features and fingernails that production rate can be increased to 360 dolls per day. Total material cost for each doll is approximately $3.50; Fisher-Price has to invest $20 in the necessary supplies (expendables) per day; energy costs are assumed to be only $4.00 per day, and you think that employees should be making $10 per hour for their time. a) Viewing this from a total (multifactor) productivity perspective, what is Fisher-Price's productivity at present and with the new paint? (2 POINTS) b) How would total (multifactor) productivity change if using the new paint raised Fisher-Price's material costs by $0.50 per doll? (2 POINTS) c) If Fisher-Price uses the new paint, by what amount could Fisher-Price's material costs increase without reducing total (multifactor) productivity? (2 POINTS)
