1. a restaurant customer left $3.50 as a tip. the tax on the meal was 7% and the tip was 20% of the

Explanation:

Step1: Calculate total number of people surveyed

Add the number of people in each category: \(1100 + 740+160\).
$$1100 + 740+160=(1100 + 160)+740=1260 + 740 = 2000$$

Step2: Calculate the percentage of completely - satisfied people

Use the formula \(\text{Percentage}=\frac{\text{Number of completely - satisfied people}}{\text{Total number of people}}\times100\%\).
Here, the number of completely - satisfied people is \(1100\) and the total number of people is \(2000\).
$$\frac{1100}{2000}\times100\%=\frac{1100\times100\%}{2000}=\frac{110000\%}{2000}=55\%$$

Answer:

\(55\%\)
