	iced tea	lemonade	total
adult		15
total	24		50

Explanation:

Step1: Find number of adults who prefer iced - tea

Since the total number of people who prefer iced - tea is 24 and 5 children prefer iced - tea, the number of adults who prefer iced - tea is $24 - 5=19$.

Step2: Find total number of children

Let the number of children who prefer lemonade be $x$ and the total number of children be $y$. Let the number of adults who prefer iced - tea be $a = 19$, the number of adults who prefer lemonade be $b = 15$, and the total number of people surveyed be 50. The total number of people who prefer iced - tea is 24. We know that the total number of people surveyed is 50. The total number of adults is $a + b=19 + 15 = 34$. So the total number of children $y=50-(19 + 15)=16$.

Step3: Find number of children who prefer lemonade

Since 5 children prefer iced - tea and the total number of children is 16, the number of children who prefer lemonade is $16 - 5 = 11$.

Step4: Find total number of people who prefer lemonade

The total number of people who prefer lemonade is the sum of children and adults who prefer lemonade, so it is $11+15 = 26$.

Step5: Find total number of adults

The total number of adults is the sum of adults who prefer iced - tea and adults who prefer lemonade, which is $19 + 15=34$.

Answer:

Iced Tea	Lemonade	Total
