Use the five-step plan to devise a strategy to solve each of these problems about Khianna’s family reunion. Be sure to include at least three of your module vocabulary words in your response.
1.) Look at the following problem:
At the family reunion there were 15 more family members there this year than at the last family reunion. There were 46 people at this year’s family reunion. How many family members came to the last family reunion?
Write a paragraph explaining what strategy or strategies could be used to solve this problem. Be sure to include a way in which a variable equation could be implemented:
To solve this problem, we can use the five-step plan. First, we need to identify what the problem is asking. In this case, we need to find out how many family members came to the last family reunion. Next, we need to define a variable to represent the unknown quantity. Let's say we use "x" to represent the number of family members at the last reunion. Then, we can set up an equation based on the information given in the problem. Since there were 15 more family members at this year's reunion than at the last one, we can write the equation as x + 15 = 46. This equation represents that the number of family members at the last reunion plus 15 equals the total number of people at this year's reunion. Moving on to the next step, we solve the equation to find the value of x. Subtracting 15 from both sides of the equation, we get x = 46 - 15, which simplifies to x = 31. Therefore, there were 31 family members at the last family reunion.
