Answer:
Option C.
Step-by-step explanation:
Adam's working periods in a week are
Monday = 8 hours
Tuesday = 4[tex]\frac{1}{4}=\frac{17}{4}[/tex] hours
Wednesday = [tex]6\frac{1}{8}=\frac{49}{8}[/tex] hours
Thursday = [tex]7\frac{1}{4}[/tex] = [tex]\frac{29}{4}[/tex] hours
Friday = [tex]8\frac{1}{8}=\frac{65}{8}[/tex] hours
Therefore, total working hours = 8 + [tex]\frac{17}{4}+ \frac{49}{8}+ \frac{29}{4}+ \frac{65}{8}[/tex]
= 8+[tex]\frac{(17+29)}{4}+\frac{(49+65)}{8}[/tex]
= 8+[tex]\frac{46}{4}+\frac{114}{8}[/tex]
= 8+[tex]\frac{92+114}{8}[/tex]
= 8+[tex]\frac{206}{8}[/tex]
= [tex]\frac{64+206}{8}[/tex]
= [tex]\frac{270}{8}[/tex]
= [tex]\frac{135}{4}[/tex]
= [tex]33\frac{3}{4}[/tex] hours
Therefore, Option C. is the answer.
