• The circle graph above gives the distribution of salad dressing chosen by customers at a restaurant. If approximately 200 customers order each day at the restaurant. Which of the following is closest to the difference per day between the number who choose Italian dressing and the number who choose vinaigrette dressing? Blue cheese 20% French 5% Italian 45% Vinaigrette 30%

Answer: 30

Explanation: To find the difference between the number of customers choosing Italian dressing and those choosing vinaigrette, we need to calculate the number of customers for each dressing type based on the percentages given in the circle graph. Then, subtract the number of vinaigrette customers from the number of Italian dressing customers.

Steps:

1. Identify the percentages:

• Italian dressing: 45%
• Vinaigrette dressing: 30%

1. Calculate the number of customers for each dressing:

• Total customers per day = 200
• Italian dressing customers = \( 200 \times \frac{45}{100} = 90 \)
• Vinaigrette dressing customers = \( 200 \times \frac{30}{100} = 60 \)

1. Find the difference:

• Difference = Italian dressing customers – Vinaigrette dressing customers
• Difference = \( 90 - 60 = 30 \)

Thus, the difference per day between the number who choose Italian dressing and the number who choose vinaigrette dressing is 30.
