20.- The circle graph 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 chose vinaigrette dressing?

a) 10 Salad Dressing.

Explanation

Determine the percentage of customers who choose Italian dressing from the graph, which is 40%.
Determine the percentage of customers who choose Vinaigrette dressing from the graph, which is 30%.
Calculate the difference in percentage between Italian dressing and Vinaigrette dressing, which is 40% – 30% = 10%.
Convert the percentage difference to a number by multiplying it by the total number of customers, which is 200. So, 10% * 200 = 20.
