My question is: A cafe has a few orders to cook and also needs to makes sandwiches for a group of customers that arrived. 3 local offices have each ordered 10 bacon sandwiches and half of the group that has arrived have asked for 4 bacon sandwiches each. If the cafe makes a total of 54 bacon sandwiches, how many customers are in the group of customers that arrived? Your thoughts:
The offices ordered a total of 3 offices * 10 sandwiches each = 30 sandwiches. So the group of customers must have ordered 54 total sandwiches 30 sandwiches for the offices = 24 sandwiches. This is a total of 24 sandwiches / 4 sandwiches per customer = 6 customers who ordered a sandwich. As only half the group ordered a bacon sandwich, the entire group must have consisted of 6 customers * 2 = 12 customers. The final answer: 12.
