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

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

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
