In the deli section at a grocery store, customer tag numbers 157 through 265 were served. How many customers were served that day?
AnswerThis is an inclusive type problem where you need to find out how many people in a group
Since we need to include person 157, we do the following formula
People in the group = Maximum Person - Minimum Person + 1
People in the group = 265 - 157 + 1
People in the group = 109
