Kate is at a T-shirt sale where she can buy one and get a second one for 30% off. She wants to buy two T-shirts listed at $19 each. How much will she pay?

So in this problem we can state that each T-shirt costs S19 each. And if Kate buys two she gets a 30% off with the second shirt she buys. And how much will she pay?

Solution:

1. 19 for each t-shirt

2. Total of $38 if not provided with 30% off

3. 19 x 0.3 = 5.7

4. Hence 30% of $19 is $5.7

5. Next is we deduct $5.7 which is 30% of $19.

6. 19 - 5.7 = $13.3

7. Therefore we add one shirt for $19 and the second, less 30% off which now only costs for $13.3.

8. 19 + 13.3 = 32.3

9. Conclusively, she will pay $32.3 for the shirts.
