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. <span>And how much will she pay?
Solution:</span> <span><span> 1. </span>19 for each t-shirt</span> <span><span> 2. </span>Total of $38 if not provided with 30% off</span> <span><span>3. </span>19 x 0.3 = 5.7</span> <span><span>4. </span>Hence 30% of $19 is $5.7</span> <span><span>5. </span>Next is we deduct $5.7 which is 30% of $19.</span> <span><span> 6. </span>19 – 5.7 = $13.3</span> <span><span> 7. </span>Therefore we add one shirt for $19 and the second, less 30% off which now only costs for $13.3.</span> <span><span> 8. </span>19 + 13.3 = 32.3</span> <span><span>9. </span>Conclusively, she will pay $32.3 for the shirts.</span>
