The company estimates that testing reveals design problems 10% of the time and implementation errors 40% of the time. Question 1: What is the average time implementation is visited? Your answer: D.1429 Question 2: Knowing that design, implementation, and testing cost on average are 10005, 2000$, and 500$ respectively, find the average cost in 5 of a released software.
