Answer:
Total cost of jersey = $210
Option A is correct option
Explanation:
Original price of jersey = $250
Sale price is 20% of Original price i.e 20% off $250
Now finding 20% off 250
![20\% \ of \ 250\\=(20)/(100)* 250\\=50](https://img.qammunity.org/2021/formulas/mathematics/high-school/q0ejn98hfqa9cxr61bmzibkcjowc8xlne4.png)
So there will be discount of $50
The Price of jersey after 20% discount is: 250-50 = 200
Sale Price of jersey = $200
Now we add 5% GST
5% off 200
![5\% \ of \ 200\\=(5)/(100)* 200\\=10](https://img.qammunity.org/2021/formulas/mathematics/high-school/xrsazc4z9a5mn7ngjvwqbgzsw2ix4219vc.png)
So, GST amount is $10
Total cost of jersey = Sale Price + GST
Total cost of jersey = $200+$210
Total cost of jersey = $210
Option A is correct option
