If milk is selling for $87.05 per liter, how many liters can you buy with $20?

1. 0.25 L

2. 0.50 L

3. 0.75 L

4. 0.23 L

The correct answer is: 0.23 L

To determine how many liters of milk can be purchased with $20 when the price is $87.05 per liter, the process involves dividing the total amount of money available ($20) by the price per liter ($87.05). Calculating this gives: \[ \text{Liters} = \frac{20}{87.05} \approx 0.2295 \] Rounding this to a reasonable number of decimal places leads us to approximately 0.23 liters. This is the correct quantity you would be able to purchase for $20. Other potential answers provide quantities that either exceed the amount of milk you can afford with $20 or do not accurately reflect the division of the two amounts involved in this scenario. Overall, the computation confirms that 0.23 liters is the precise amount you would obtain, reflecting a clear understanding of unit price calculations.
