in spring, a tree needs 315 ml of fertilizer. if fertilizer is sold in a 4.1-l bottles, how many bottles are needed to fertilize 30 trees.

To determine how many bottles of fertilizer are needed to fertilize 30 trees, we can follow these steps:

1. **Amount of fertilizer per tree**:  
   Each tree requires 315 mL of fertilizer.

2. **Total amount of fertilizer needed for 30 trees**:  
   Multiply the amount of fertilizer per tree by the number of trees:
   \[
   315 \, \text{mL/tree} \times 30 \, \text{trees} = 9450 \, \text{mL}
   \]

3. **Convert the total fertilizer needed to liters**:  
   Since 1 liter (L) = 1000 milliliters (mL), we convert 9450 mL to liters:
   \[
   9450 \, \text{mL} = \frac{9450}{1000} = 9.45 \, \text{L}
   \]

4. **Determine how many bottles are needed**:  
   Each bottle contains 4.1 liters of fertilizer. To find out how many bottles are needed, divide the total amount of fertilizer by the amount in each bottle:
   \[
   \frac{9.45 \, \text{L}}{4.1 \, \text{L/bottle}} \approx 2.3 \, \text{bottles}
   \]

Since we cannot buy a fraction of a bottle, you'll need to purchase **3 bottles** to have enough fertilizer for 30 trees.

Would you like more details on any step?

Here are some related questions for further practice:
1. How many trees can be fertilized with one 4.1 L bottle?
2. If the fertilizer is sold in 500 mL bottles, how many would you need for 30 trees?
3. How much fertilizer is left over if only 2 bottles are bought for 30 trees?
4. How much fertilizer is needed for 50 trees instead of 30?
5. What if each tree required 400 mL of fertilizer instead?

**Tip**: Always remember to convert units (like mL to L) when necessary for accurate results.
