Answer:
Number of sand bags needed = 124
Step-by-step explanation:
Diameter of garden = 40 yd
Width of path = 6 yd
Diameter of garden with path = 40 + 2 x 6 = 52 yd
We need to find area of path.
Area of path = Area of garden with path - area of garden
![\texttt{Area of path = }\frac{\pi \times 52^2}{4}-\frac{\pi \times 40^2}{4}\\\\\texttt{Area of path = }867.08yd^2](https://tex.z-dn.net/?f=%5Ctexttt%7BArea%20of%20path%20%3D%20%7D%5Cfrac%7B%5Cpi%20%5Ctimes%2052%5E2%7D%7B4%7D-%5Cfrac%7B%5Cpi%20%5Ctimes%2040%5E2%7D%7B4%7D%5C%5C%5C%5C%5Ctexttt%7BArea%20of%20path%20%3D%20%7D867.08yd%5E2)
Area covered by one sand bag = 7 yd²
![\texttt{Number of sand bags required = }\frac{\texttt{Area of path}}{\texttt{Area covered by one sand bag}}\\\\\texttt{Number of sand bags required = }\frac{867.08}{7}=123.86\approx 124](https://tex.z-dn.net/?f=%5Ctexttt%7BNumber%20of%20sand%20bags%20required%20%3D%20%7D%5Cfrac%7B%5Ctexttt%7BArea%20of%20path%7D%7D%7B%5Ctexttt%7BArea%20covered%20by%20one%20sand%20bag%7D%7D%5C%5C%5C%5C%5Ctexttt%7BNumber%20of%20sand%20bags%20required%20%3D%20%7D%5Cfrac%7B867.08%7D%7B7%7D%3D123.86%5Capprox%20124)

= 224.6
Add the salary and the commission,
450.00 + 224.6
