Answer: Total weekly cost was $230.4.
Step-by-step explanation:
Since we have given that
Number of hours Sue worked on Monday = [tex]6\frac{3}{4}=\frac{27}{8}\ hours[/tex]
Number of hours Sue worked on Tuesday = 4 hours
Number of hours Sue worked on Wednesday = [tex]7\frac{3}{4}=\frac{31}{8}\ hours[/tex]
Number of hours Sue worked on Thursday = 8 hours
Number of hours Sue worked on Friday = [tex]5\frac{1}{2}=\frac{11}{2}\ hours[/tex]
So, Total number of hours in all five days is given by
[tex]\frac{27}{4}+4+\frac{31}{4}+8+\frac{11}{2}\\\\=12+\frac{27+31}{4}+\frac{11}{2}\\\\=12+\frac{58}{4}+\frac{11}{2}\\\\=12+\frac{58+22}{4}\\\\=12+\frac{80}{4}\\\\=12+20\\\\=32[/tex]
Cost of her wage per hour = $7.20
Total weekly wage is given by
[tex]32\times 7.20\\\\=\$230.4[/tex]
Hence, Total weekly cost was $230.4.
