It seems like you're working through a problem related to Mr. Nelson's use of potting soil for potted plants. Let's break it down step by step for each part.
Part A
To determine how many quarts of soil Mr. Nelson used per tomato plant, we need to find out how many quarts were in the entire bag of potting soil, which is 80 quarts.
Since he potted 15 tomato plants using 80 quarts, we can divide the total quarts by the number of plants.
\[ \text{Quarts per tomato plant} = \frac{80 \text{ quarts}}{15 \text{ plants}} \approx 5.33 \text{ quarts/plant} \]
So, Mr. Nelson used approximately 5.33 quarts of soil per tomato plant.
Part B
Now, we need to know how many quarts of soil Mr. Nelson used for the pepper plant. If you have a specific amount for the pepper plant's soil usage (since it seems to be missing in your query), you would just reference that quantity. Let’s say he used \( x \) quarts for the pepper plant.
So, if the amount of soil used for the pepper plant is \( x \) quarts, please provide that, and I can help you fill that in.
Part C
For the final part, if Mr. Nelson has a specific number of total plants he plans to pot (including tomato, radish, and pepper plants), we should determine if he has enough soil left to finish planting. If he used a certain amount for the pepper plant and for the tomatoes (80 quarts), you would have:
\[ \text{Total used} = \text{Quarts for pepper plant} + \text{Total quarts for tomatoes} \]
Since we already calculated the total quarts used for the 15 tomatoes to be 80 quarts, we can express it as:
\[ \text{Total used} = x + 80 \text{ quarts} \]
Then, check if the total amount exceeds the amount he has (in this case, 80 quarts). If he plans to pot another plant, you could deduct or reassess how much soil he has accordingly.
If you have specific numbers to insert in these calculations, please let me know, and I can help clarify.
