Answer:
$110.56
Explanation:
The Total Cost of the three shirts will be = $49.96*3 = $149.88
When the third shirt is discounted cost becomes = $49.96*2 = $99.92
However tax is on the initial total cost which is 7.1%*149.88 = $10.64
Therefore the amount to be paid will be the discounted price of 99.92 + tax of 10.64 = $110.56
