Explanation:

For Questions 25-30 (John Kim's Time Card)

Step1: Calculate Mon. morning hours

$11:30 - 6:45 = 4\text{h}45\text{min}$

Step2: Calculate Mon. afternoon hours

$3:45 - 12:00 = 3\text{h}45\text{min}$

Step3: Sum Mon. total, round to quarter

$4\text{h}45\text{min} + 3\text{h}45\text{min} = 8\text{h}30\text{min}$

Step4: Calculate Tue. morning hours

$11:30 - 7:00 = 4\text{h}30\text{min}$

Step5: Calculate Tue. afternoon hours

$3:45 - 12:00 = 3\text{h}45\text{min}$

Step6: Sum Tue. total, round to quarter

$4\text{h}30\text{min} + 3\text{h}45\text{min} = 8\text{h}15\text{min}$

Step7: Calculate Wed. morning hours

$11:45 - 6:56 = 4\text{h}49\text{min} \approx 4\text{h}45\text{min}$ (rounded to nearest quarter)

Step8: Calculate Wed. afternoon hours

$4:00 - 12:30 = 3\text{h}30\text{min}$

Step9: Sum Wed. total

$4\text{h}45\text{min} + 3\text{h}30\text{min} = 8\text{h}15\text{min}$

Step10: Calculate Thur. morning hours

$12:50 - 6:45 = 6\text{h}5\text{min} \approx 6\text{h}0\text{min}$ (rounded to nearest quarter)

Step11: Calculate Thur. afternoon hours

$3:00 - 1:50 = 1\text{h}10\text{min} \approx 1\text{h}15\text{min}$ (rounded to nearest quarter)

Step12: Sum Thur. total

$6\text{h}0\text{min} + 1\text{h}15\text{min} = 7\text{h}15\text{min}$

Step13: Calculate Fri. morning hours

$11:30 - 7:10 = 4\text{h}20\text{min} \approx 4\text{h}15\text{min}$ (rounded to nearest quarter)

Step14: Calculate Fri. afternoon hours

$4:25 - 12:30 = 1\text{h}55\text{min} \approx 2\text{h}0\text{min}$ (rounded to nearest quarter)

Step15: Sum Fri. total

$4\text{h}15\text{min} + 2\text{h}0\text{min} = 6\text{h}15\text{min}$

Step16: Sum all daily totals

$8\text{h}30\text{min} + 8\text{h}15\text{min} + 8\text{h}15\text{min} + 7\text{h}15\text{min} + 6\text{h}15\text{min} = 38\text{h}30\text{min}$

Step1: Calculate total hours needed

$\text{Total Hours} = \frac{\$360.75}{\$9.75} = 37$

Step2: Calculate daily hours (Mon-Thur)

$3:30\text{ PM} - 8:00\text{ AM} - 0.5\text{h} = 7\text{h}$

Step3: Calculate Mon-Thur total hours

$7\text{h} \times 4 = 28\text{h}$

Step4: Calculate Friday required hours

$37\text{h} - 28\text{h} = 9\text{h}$

Step5: Calculate Friday end time

$8:00\text{ AM} + 9\text{h} + 0.5\text{h} = 5:30\text{ PM}$

Step1: Calculate Q32 total pay

$\$3.05 \times 136 = \$414.80$

Step2: Calculate Q33 total pay

$\$2.38 \times 85 = \$202.30$

Step3: Calculate Q34 setup pay

$\$125 \times 11 = \$1375$

Step4: Calculate Q34 test ride pay

$\$18 \times 9 = \$162$

Step5: Sum Q34 total pay

$\$1375 + \$162 = \$1537$
