Question: Corna wants to buy a shirt. The store buys the shirt for $20, but charges 30% for profit. However, the shirt is on sale for 50% off the selling price. What is the price now?

Question: Sunnyvale School was having a picnic. They wanted to make fruit punch. They had 4.5 liters of orange punch. They had twice as much cherry punch as orange punch and 1.5 liters less of apple juice than cherry punch. When they combined all of the fruit juices together, how many liters of fruit punch did they have?
Answer:
Step-by-step reasoning process: Orange = 4.5 L. Cherry = 2 * 4.5 = 9 L. Apple = 9 - 1.5 = 7.5 L. Total punch = 4.5 + 9 + 7.5 = 21 L. They had 21 liters of fruit punch for the picnic.
So the answer is 21.
