Can someone help me answer this
Pani-rosa [81]

Answer:   Total hours for the week: 42

Overtime Hours: 3  (anything over 8 hours per day in most places)

Step-by-step explanation:

For each shift, subtract the starting time from the ending time.

Then add the morning hours to the afternoon hours to get the daily total. Overtime is anything more than 8 hours.

Add all the daily totals to get the weekly total.

Add the overtime hours from any days with over 8 hours.

For example:

Tuesday:  morning 11:00 - 7:00 = 4 hours. afternoon 17:00 - 12:00 = 5 hours

4 + 5 = 9 hours daily total.  9 - 8 = 1 hour overtime

<em>You can convert hours to minutes to figure times like 10:30 - 9:00</em>

<em>1 hour - 60 minutes, So from 9 to 10am is one hour 60-30 = 30. 30/60 =1/2</em>

<em>Then you can convert the fraction to a decimal 1/2 = .5  </em>

<em>So 10:30 - 9:00  is 1:30  changed to a decimal is 1.5 hours. </em>
