Due to technology changes, the current equipment will become obsolete at the end of period 15. If a new machine costs $2000, and the net revenue earned per unit is $10, how many machines should be added between today (t=C) and the end of period 15? In this question, ignore the capacity utilization limitation in questions 3 and 4. 1 If, due to demand variation around the mean, it has been decided that capacity should be added whenever utilization is projected to exceed 80%, in what time period would this occur for the current capacity (200 units/period)? O Period 3 Period 4 Period 5 Period 6 Period 7 Question 4 2 pts If two machines are added to the existing four, in what time period would the 80% utilization limit be exceeded? Period 9 Period 10 Period 11 Period 12 Period 13 Demand is forecasted using the following regression equation: D = 100+ 15(t) where "t" is a specified future time period. The current time period is 0 (t=0). The machines used to make this product have a capacity of 50 units/time period. The company currently has 4 machines yielding a total capacity of 200 units/time period
