Sally sold 20 cups of lemonade last week. She sold 30% more lemonade this week. How many cups of lemonade did she sell in total for both weeks? Let's answer step by step:
If Sally sold 30% more lemonade this week, she sold 20 * 30 / 100 = 6 more cups this week. This week, Sally sold 20 + 6 = 26 cups of lemonade. In total for both weeks, Sally sold 20 + 26 = 46 cups of lemonade. The answer: 46.
