The circle graph above gives the distribution of salad dressing chosen by customers at a restaurant. If approximately 200 customers order salad 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?
A. 10
B. 15
C. 20
B. 15
C. 20
Introduction:
The circle graph represents the distribution of salad dressing choices made by customers at a restaurant. The question asks us to determine the difference in the number of customers choosing Italian dressing versus Vinaigrette dressing, based on a total of approximately 200 customers ordering salad daily.
Explanation:
-
Step 1: Review the circle graph and identify the percentage of customers who choose Italian and Vinaigrette dressing.
-
Step 2: Multiply the percentage of customers who select each dressing by the total number of customers (200) to calculate the approximate number of customers for each dressing.
-
Step 3: Subtract the number of customers choosing Vinaigrette from those choosing Italian dressing to find the difference.
Solution:
If the circle graph indicates that:
-
40% of customers choose Italian dressing
-
30% of customers choose Vinaigrette dressing
The calculations would be as follows:
-
Italian dressing: 40% of 200 = 0.40 * 200 = 80 customers
-
Vinaigrette dressing: 30% of 200 = 0.30 * 200 = 60 customers
The difference between the number of customers who choose Italian and Vinaigrette dressing is:
-
80 - 60 = 20 customers
Thus, the answer is closest to C. 20.
