Christmas Express makes wreaths in batch sizes of 15. The cutting & assembly process takes 2 minutes per wreath and the decorating process time is 15 minutes per wreath. It takes 5 minutes to move the wreaths from the cutting & assembly process to the decorating process.

Compute the value-added, non-value-added, and the total lead time of the wreath process.

Value-added lead time:
Non-value-added lead time:
	Move time
	Within batch wait time
Total lead time
