Standard time is calculated by multiplying the normal time by both the performance rating and the allowance factor. Here, the normal time is 12 minutes, and the performance rating is 0.80, which gives us 12 * 0.80 = 9.6 minutes. The allowance is 20% of the job time, so we add 20% of 12 minutes (2.4 minutes) to the 9.6 minutes, resulting in a total of 12 minutes. However, to find the standard time, we should actually apply the allowance to the time after adjusting for the performance rating. The correct calculation is to first find the time adjusted for performance, then increase it by the allowance percentage to find the standard time. The correct approach involves adjusting the initial calculation to correctly apply the allowance on top of the performance-adjusted time, leading to a standard time that accounts for both the performance rating and the allowance. The correct calculation is: 12 minutes (normal time) * 0.80 (performance rating) = 9.6 minutes, then adding the 20% allowance on the normal time, not on the performance-adjusted time, was a mistake in the explanation. The correct way to include the allowance is to apply it to the performance-adjusted time, which would actually result in a different standard time than the options provided, indicating a misunderstanding in the initial explanation. The proper calculation for standard time should consider both the performance adjustment and the correct application of the allowance.
