Final answer:
The number of shirts Dante bought was determined by dividing his total cost by the price of two shirts with the sale. He bought 3 pairs of shirts, totaling 6 shirts.
Step-by-step explanation:
To determine the number of shirts Dante bought, we need to calculate how many pairs of shirts he could've purchased with $103.41 given the buy one, get one 50% off sale. The first shirt would be full price at $22.98, and the second shirt would be half of that, which is $11.49. The total cost for two shirts, one full price and one half off, would be $22.98 + $11.49 = $34.47.
Now, to find how many pairs of shirts Dante could buy, we divide the total amount spent, $103.41, by the cost of two shirts, which is $34.47. Dividing $103.41 by $34.47, we get approximately 3. So, Dante bought 3 pairs of shirts, which is 6 shirts in total.
