The hundredth-hour method rounds the fraction of an hour to the nearest hundredth. 
So, 8 minutes is equivalent to 0.13 hours and 24 minutes is equivalent to 0.40 hours. 
Therefore, 
40.00 + 0.13 + 8.40 = 48.53 hours (total hours worked in hundredths)
Rounding to the nearest hundredth gives: 
48.53 ≈ 48.54 hours
Dividing by 1.2 gives: 
48.54 / 1.2 = 40.45 hours (rounded to two decimal places)
Therefore, Brandie worked 40.27 hours that week. (option C)
