Katrina has 14 flower seeds. She needs 40 seeds to start her garden. Which number sentence shows how many seeds Katrina should buy? A. \( 14-\square=40 \) B. \( 14+40=\square \)

To determine how many seeds Katrina should buy, we need to find the difference between the number of seeds she needs (40) and the number of seeds she currently has (14). We can set up the equation as follows: \[ \text{Seeds needed} = \text{Total seeds needed} - \text{Seeds she has} \] This can be expressed as: \[ \text{Seeds needed} = 40 - 14 \] So, the correct number sentence that shows how many seeds Katrina should buy is: \[ 14 + \square = 40 \] This means that the answer is: **A. \( 14 - \square = 40 \)** is incorrect because it suggests subtracting from 14 to reach 40, which doesn't make sense in this context. **B. \( 14 + 40 = \square \)** is also incorrect because it adds the seeds she has to the total needed, which is not the right approach. The correct formulation should be \( \square = 40 - 14 \), which is not listed among the options. However, if we were to express it in terms of how many seeds she needs to buy, it would be: \[ \square = 40 - 14 \] Thus, the correct answer is not explicitly listed, but the logic leads us to conclude that she needs to buy \( 40 - 14 = 26 \) seeds.
