Refer to the table below. Assume that the company involved now finds that the learning rate is 78 percent. The 78 percent learning rate coefficient is -0.358454; that is b = -0.358454 in the formula Y = aX^b.

Required:

Using the formula, Y = aX^b, compute the labor time and costs for 5, 6, and 7 units. (Round your intermediate calculations (except for coefficient) and final answers to 2 decimal places.)
