just need answer, steps are appreciated though

A baker is responsible to fill and empty 5 ovens in a large industrial bakery. It takes 2.5 hours to empty and fill each oven, following an exponential service time pattern. Once an oven is filled the contents bake for 6.4 hours before they require emptying and refilling. Bakers are paid $15 per hour. If an oven is not emptied at exactly 6.4 hours the contents will be overbaked and ruined. The cost of having an oven go unattended is $60 per hour. Based on lowest total cost, how many bakers should be staffed and what is the cost? Here are the corresponding values from table D.8 Finite queuing tables for a population of N=5. M1...F = 0.661, M2...F=0.938, M3...F=0.993. Note: the D values from the table are not required to answer this question.
