0% 10% 20% 30% 40% 50% 60% 70%

Explanation:

Step1: Find the percentage of customers who prefer chocolate or vanilla

The percentage of customers who prefer chocolate is 19% and who prefer vanilla is 61%. Add these percentages: $19\%+61\% = 80\%$.

Step2: Calculate the number of customers who prefer chocolate or vanilla

The total number of customers is 16500. To find 80% of 16500, use the formula $n = 0.8\times16500$.
$n=0.8\times16500 = 13200$.

Answer:

13200
