Question
Mr. and Mrs. Ortega had 10 people over for dinner. There were 7 adults, and the rest were kids.The letter k stands for the number of kids. Which equation can you use to find k?
Solution
The total number of people is the sum of the adults and the kids. We know the total number of people is 10 and the number of adults is 7. We can represent the number of kids as k. So, the equation to find the number of kids would be:
7 (adults) + k (kids) = 10 (total people)
So, you can use the equation 7 + k = 10 to find the number of kids.
