A local café serves tea, coffee, cookies, scones, and muffins. They recently gathered data about their customers who purchase both a drink and a snack. The frequency table below shows the results of the survey.

If approximately [tex]24\%[/tex] of the customers surveyed have a scone with their tea and approximately [tex]36\%[/tex] of the customers surveyed buy a muffin, complete the column and row headings for the given table.

[tex]
\[
\begin{tabular}{|c|c|c|c|c|}
\hline
& \text{Cookie} & \text{Muffin} & \text{Scone} & \text{Total} \\
\hline
\text{Tea} & 40 & 100 & 110 & 250 \\
\hline
\text{Coffee} & 120 & 80 & 50 & 250 \\
\hline
\text{Total} & 160 & 180 & 160 & 500 \\
\hline
\end{tabular}
\]

Answer :

To solve the problem, let's carefully analyze the table and the given percentages.

We know that:
- The total number of customers surveyed is 500.
- 24% of customers have a scone with their tea.
- 36% of customers buy a muffin.

Let's determine the missing labels for the frequency table.

1. Calculate the number of customers who have a scone with their tea:

Since 24% of the surveyed customers have a scone with their tea, we calculate that number by taking 24% of the total number of surveyed customers:

[tex]\[
\text{Scone with Tea} = \frac{24}{100} \times 500 = 120
\][/tex]

2. Calculate the total number of customers who buy a muffin:

Given that 36% of all customers surveyed buy a muffin, we can calculate this as:

[tex]\[
\text{Muffin Total} = \frac{36}{100} \times 500 = 180
\][/tex]

Now, let's complete the column and row headings according to the given data:

The two main rows, which distinguish the type of drink, and the three main columns, which distinguish the type of snack, should look like this:

- Rows:
- First row: Tea (total number of "Tea" customers is 250)
- Second row: Coffee (total number of "Coffee" customers is 250)

- Columns:
- First column: Cookie (total number of "Cookie" customers is 160)
- Second column: Muffin (total number of "Muffin" customers is 180)
- Third column: Scone (total number of "Scone" customers is 160)

Using these calculations and labels, the complete table would look like this:

[tex]\[
\begin{array}{|c|c|c|c|c|}
\hline
& \text{Cookie} & \text{Muffin} & \text{Scone} & \text{Total} \\
\hline
\text{Tea} & 40 & 100 & 110 & 250 \\
\hline
\text{Coffee} & 120 & 80 & 50 & 250 \\
\hline
\text{Total} & 160 & 180 & 160 & 500 \\
\hline
\end{array}
\][/tex]

Thus, the columns and rows have been correctly labeled based on the data and survey conclusions.
