Question

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?unt?

Answer 1

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.
