1. A time study analyst timed an assembly operation for 30 cycles, and then computed the average time per cycle, which was 18.75 minutes. The analyst assigned a performance rating of .96, and decided that an appropriate allowance was 15%. Assume the allowance factor is based on the workday. Determine the following: observed time (OT), the normal time (NT), and the standard time (ST)

1. observed time = 18.75 minutes.

2. Normal time = 18 minutes

3. Standard time = 21.17 minutes

Explanation:

1. The observed time will be equal to the average time per cycle, which was given in the question as 18.75 min. Therefore, observed time = 18.75 minutes.

2. The normal time will be:

= Average Time x Performance Rating

= 18.75 x 0.96

= 18 minutes

3. The standard time will be:

= Normal time × 1/(1 - 15%)

= Normal time × 1/(1 - 0.15)

= 18 × 1/0.85

= 18 × 1.176

= 21.17 minutes

month 1 start amount =$3287.90 interest=(3287.90x0.0145/12)3.97 total to pay=$3291.81 paid =$1200 balance =$2,091.87

month 2 starting amount= $2,091.87 interest =$25.28 total to pay =$2117.15 paid =$1200 balance $917.15

month 3 starting amount =$917.15 interest =$11.08 total to pay =$928.23 paid =$928.23 balance =$0 total to pay 1200+1200+928.23 = $3328.23 it will take 3 months to pay a total of $3328.23

answer; i believe the answer is 40,600,000;
