Answer:
Total percent of customers who order a drink with their entrée = 76%
Step-by-step explanation:
Let
Total customers = 100%
customers who order a meat entrée = 90%
customers who order a vegetarian entrée = 10%
Of the customers who order a meat entrée, 80% order a drink
% of customers who order a meat entrée and drink = 80% of 90%
= (80/100 * 90/100) * 100
= (0.8 * 0.9) * 100
= 0.72 * 100
= 72%
% of customers who order a meat entrée and drink = 72%
Of the customers who order a vegetarian entrée, 40% order a drink.
% of customers who order a vegetarian entrée and drink = 40% of 10%
= (40/100 * 10/100) * 100
= (0.4 * 0.1) * 100
= 0.04 * 100
= 4%
% of customers who order a vegetarian entrée and drink = 4%
What is the percent of customers who order a drink with their entrée?
Total percent of customers who order a drink with their entrée = % of customers who order a meat entrée and drink + % of customers who order a vegetarian entrée and drink
= 72% + 4%
= 76%
Total percent of customers who order a drink with their entrée = 76%
