Answer: The seasonal relatives is calculated are as follows:
Explanation:
Given that,
restaurant only open from Wednesday to Saturday,
- 29 percent of its business on Friday
- 31 percent on Saturday night
- 21 percent on Thursday night.
∴ The remaining 19% of its business he does on Wednesday
Now, suppose that total production of sales in a given week be 'y'
So, average sales in a week =
![(y)/(4)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/abyo3hh7ku99fps467eq18j2ott762i879.png)
If we assume that y = 1
hence, average sales in a week =
![(1)/(4)](https://img.qammunity.org/2020/formulas/mathematics/high-school/iiq2xsk4vi9pqjukqb60xxgyxukyno498i.png)
= 0.25
Now, we have to calculate the seasonal relatives,
that is,
=
![(Sales in a given day)/(average sales in a week)](https://img.qammunity.org/2020/formulas/mathematics/college/7fen36vzyo7q77z0fowedj7t9inhwd18jx.png)
Wednesday:
=
![(0.19)/(0.25)](https://img.qammunity.org/2020/formulas/mathematics/college/sbm0e3e7hhtelq52fybzag2u6qzaa8jkdb.png)
= 0.76
Thursday:
=
![(0.21)/(0.25)](https://img.qammunity.org/2020/formulas/mathematics/college/78dxjwtd8ncg3l0a93pycoy4bxc22sb32f.png)
= 0.84
Friday:
=
![(0.29)/(0.25)](https://img.qammunity.org/2020/formulas/mathematics/college/l52l1p53wt7a7ltl9go16ewmeellgysjbw.png)
= 1.16
Saturday:
=
![(0.31)/(0.25)](https://img.qammunity.org/2020/formulas/mathematics/college/s5xb0knf4miw7lwqsxxvndk7dh58jjy2w0.png)
= 1.24
