To determine what percent of the to-go orders were delivery orders placed by phone from the given two-way frequency table, follow these steps:
1. Identify the total number of to-go orders:
- According to the table, the total number of orders is 191.
2. Identify the number of delivery orders placed by phone:
- Based on the table, the number of delivery orders placed by phone is 28.
3. Calculate the percent of delivery orders placed by phone:
- Use the formula:
[tex]\[
\text{percent\_delivery\_by\_phone} = \left(\frac{\text{delivery\_by\_phone}}{\text{total\_orders}}\right) \times 100
\][/tex]
- Plug in the identified values:
[tex]\[
\text{percent\_delivery\_by\_phone} = \left(\frac{28}{191}\right) \times 100
\][/tex]
- Calculating this gives:
[tex]\[
\text{percent\_delivery\_by\_phone} \approx 14.659685863874344
\][/tex]
4. Round the result to two decimal places:
- The result rounded to two decimal places is approximately 14.66.
Therefore, the correct answer is [tex]\( B. 14.66 \% \)[/tex].
