1) If a company took 200 hours to assemble their first unit and 160 hours to assemble the second unit, we might expect it to take:

128 hours to assemble the third unit.

128 hours to assemble the fourth unit.

144 hours to assemble the third unit.

144 hours to assemble the fourth unit.

2) The first unit required 9800 hours to manufacture. The company expects to experience an 88% unit learning curve. Estimate the hours of the 20th unit. (Round intermediate calculations to 4 decimal places)
