Main Answer:
John requires 180 lunches for 12 units with 15 volunteers each. Multiply 12 by 15 to obtain the total.
Step-by-step explanation:
In the given scenario, there are 12 units in the hospital, and each unit has 15 volunteers. To find out the total number of volunteers, we multiply the number of units by the number of volunteers in each unit. So, 12 units * 15 volunteers per unit equals 180 volunteers in total. Since John is ordering lunch for each volunteer, he needs to order 180 lunches.
To break it down further, the multiplication of units and volunteers per unit is a straightforward way to calculate the total number of volunteers. Each unit represents a group of volunteers, and by multiplying the units by the volunteers in each unit, we account for all individuals. Therefore, the product of 12 units and 15 volunteers accurately gives us the total count of volunteers, which is 180. Consequently, John should order 180 lunches to ensure every volunteer in the hospital is catered for during lunchtime.
This efficient calculation method avoids the need for counting each volunteer individually, providing a quick solution for determining the overall lunch requirements. It showcases the practical application of multiplication in real-world scenarios, simplifying complex calculations for logistical planning.
