This is what I have so far. I don't know if the answers are right

Learning Curve Sharon Glessing, controller for Janson Company, has noticed that the company faces a 80 percent learning rate for its specialty design line. In planning the cost of the latest design, Sharon assumed that the first set of units would take 1,100 di labor hours. She decided to use this information in budgeting for the cost of the total project, which would involve the manufacture of 16 sets. Direct labor is paid $45 per hour. Required: 1. Complete the table below showing results by row for total production of: one unit, two units, four units, eight units, and sixteen units. (Round hour answers to two significant digits.) (Round Cumulative Total Time answers to the nearest who number.) Cumulative Number Cumulative Total Time: of Units Cumulative Average Time per Unit in Hours 1,100 Labor Hours 1 1,100 2 880 1,760 2,816 4 704 8 563 451 4,504 7,216 16 2. What is the total labor cost if Janson Company makes eight sets? Sixteen sets? (Use the rounded answers in the subsequent computations). 202,680 Total labor cost for eight sets Total labor cost for sixteen sets $ 115,456 3. Using the logarithmic function, complete the table below showing results by row for each of unit sets one through eight. (Round hour answers to two significant digits.)
