A company is producing a new product. Due to the nature of the​ product, the time required to produce each unit decreases as workers become more familiar with the production procedure. It is determined that the function for the learning process is T9x0=3+08(1/x)​, where T(x) is the​ time, in​ hours, required to produce the xth unit. Find the total time required for a new worker to produce units 1 through ​5; units 15 through 20.
