Quizplus · Accepted Answer

To estimate the time required to produce the 25th through 30th units, we can use the following formula: 
Time = (Units - 2) x Assembly time per unit
Time = (30 - 2) x (10.4 + 8.8) hours
Time = 28 x 19.2 hours
Time = 537.6 hours
However, we only need to estimate the time required for 6 units, so we can divide this total time by 14 (the number of units between the 2nd and 30th). 
Time = 537.6 hours / 14
Time ≈ 38.4 hours
Therefore, the best choice is C) 29 hours (the closest option to our estimated time).
