Step-by-step explanation:
Job pays "d" dollars per year and there are 52 weeks in a year. So to find 3 weeks pay we can write:
![(3)/(52)*d](https://img.qammunity.org/2020/formulas/mathematics/middle-school/hlu19ekffocmg8tnblntkdz9948b9jti55.png)
The agency fee is basically 18% of that. 18%, in decimal, means 0.18
Note: to get percentage to decimal, we divide by 100, so 18% means 18/100=0.18, in fraction, it is 18/100 or 9/50
THus, the fee is
![((9)/(50))((3)/(52)*d)\\=(27)/(2600)d](https://img.qammunity.org/2020/formulas/mathematics/middle-school/zzxybsuuu8qxgv30680ymvualn1d6v9jq4.png)
