The number of minutes it takes for a worker to assemble a particular item depends on his/her experience in performing the job. The average assembly time can be modelled by the following function A(t)= 20 + 3t/t + 1 , where t =number of days on the job, and A(t) is measured in minutes. An expert can assemble an item in 3 minutes. A worker is said to be proficient (very good) if they can assemble an item in 5 minutes.
Evaluate A(t) for t = 0 and as t -> +infinity. Interpret your answer. State practical domain for this function
. How many days(weeks) does it take for a worker to get proficient?
