B)0.75
C)0.80
D)0.85
E)0.90

The learning curve of 75% (0.75) would yield approximately this result. The time for the first unit is 10 minutes, and with a 75% learning curve, each subsequent unit would take 75% of the time of the previous unit. Calculating the time for the first four units under this curve: 10 (first unit) + 7.5 (second unit, 75% of 10) + 5.625 (third unit, 75% of 7.5) + 4.21875 (fourth unit, 75% of 5.625) = 27.34375 minutes, which is approximately 30 minutes.
