To track the numbers of children and adults that came into the restaurant, Chad would need to count each group separately and record the numbers. He could use a tally system or simply write down the number of children and adults in a notebook or on a piece of paper.
Here's an example of how Chad may have tracked the numbers:
Time: 12:00 PM - 1:00 PM
Children:
1. Family with 2 children
2. Group of 5 children
3. Couple with 1 child
Total children: 2 + 5 + 1 = 8
Adults:
1. Couple
2. Family with 3 adults
3. Group of friends with 4 adults
Total adults: 2 + 3 + 4 = 9
In a restaurant Chad tracked the numbers of children and adults that came in over an hour
