Read the following prompt and type your response in the space provided.

Karen is writing a word problem that can be represented by the equation 3x + 2 = 20.

A box weighs 3 pounds and several 2 pound books are put in the box. The total weight of the box and books is 20 pounds. How many books are in the box?

Does her word problem fit the equation? Justify your response.

Question 7 options:

Yes, the word problem fits the equation. The equation 3x + 2 = 20 represents the total weight of the box and books, where 3x represents the total weight of the books (with x books each weighing 2 pounds) and 2 represents the weight of the box itself. By substituting the values in the word problem into the equation, we can see that it is consistent. 3x + 2 = 20 becomes 3(2) + 2 = 20, which simplifies to 6 + 2 = 20, and ultimately 8 = 20, showing that this is not a valid solution. Therefore, the word problem does not fit the equation.
