The answer to problem 4 is equipment cost rate = 10.91%

Please help solve problem 5, thanks!

A production machine has an initial cost of $85,000. It is projected to operate for 6 years. The manufacturing is set up to run in 2 shifts: a day shift of 8 hours and a night shift of 6 hours. The day shift operates MF, but the nightshift only operates M-Th. If the overhead is 25%, determine the equipment cost rate. You have a process where parts are batched. Assume your answer in Problem 4 applies here for the cost. In addition, material cost for each part is $3.00. The batch quantity is 80 . The process time in the operation is 5.5 minutes. The time to load and unload each piece is 90 seconds. Your tool cost is $5.00 and each tool can be used for 20 pieces before it needs to be changed, which takes 4 minutes and 20 seconds. Before production can begin, the machine must be set up, which take 4.0 hours. The hourly wage of the operator is 22.50 dollars per hour. The overhead rate is 35%. Part A: Determine the cycle time for the piece. List your equation and your answer. Include your units. Part B: Determine the average production rate when the setup is included. List your equation and your answer. Include your units. Part C: Calculate the cost per piece. Use your equipment cost estimate from Problem 4. List your equation and your answer. Include your units
