Ky wants to buy three shirts, which were originally priced $49.96 each. the store will discount the price of the third shirt and then apply a 7.1% tax to the total cost of all three shirts. including the tax, what will be the mean cost of each shirts? show your work.

The price of the first shirt is PriceS1=$49.96.
The price of the second shirt is PriceS2=$49.96.
The price of the third shirt is PriceS3= $49.96 - ($49.96*%discount)
The total price is shown below:
Total Price= $49.94 + $49.96 + ($49.96-($49.96*%discount))
Total cost, 7.1% should be applied to the total price. Thus, we have:
Total cost= Total price + (total price*0.007)
Mean cost of each shirt, we divide the total cost by 3:
Mean cost = Total cost/3

The answer is the numbers between =5 and 5
