Ketut is organizing a barbecue for his parents. He knows that 13 of his mom’s friends prefer hot dogs and 9 of his dad’s friends prefer hamburgers. He organizes a two-way table to determine what he needs to buy. Which describes the variables he can use in the first row and first column of his table?

A two-way table organizes information by two categories. Here, one variable is which parent the friends are connected to (mom or dad), and the other is their meal choice (hot dogs or hamburgers). The numbers of friends belong in the table’s cells, not as a variable, so the correct choice is “parent and meal choice.”
