A grocery store has a gallon of milk for $2.30. They also have a 4 litter container of milk for $2.30. Which is the better buy and why?
Please somebody help me with this question?
So far I did
Gallon 1 = x
liter 3.79 4
4 = 3.79x cross out
divide 3.79 3.79
x=1.055 gallon
I'm not sure of your numbers, but since 1 gallon equals 3.785 (3.794?) liters, then the 4 liter container is the better buy. You'll get almost a quarter liter more for the same price.

To determine which option is the better buy, we need to compare the prices per unit.
For the gallon of milk:
Price = $2.30
Volume = 1 gallon
For the 4-liter container of milk:
Price = $2.30
Volume = 4 liters
To compare these two options, we need to convert the volume of the 4-liter container into gallons.
1 liter is approximately 0.264172 gallons (let's round it to 0.26 for simplicity).
So, 4 liters would be approximately 4 * 0.26 = 1.04 gallons.
Now, let's calculate the price per gallon for each option:
Price per gallon for the gallon of milk = $2.30 / 1 gallon = $2.30/gallon
Price per gallon for the 4-liter container = $2.30 / 1.04 gallons = $2.21/gallon (rounded to two decimal places).
Comparing the two prices, we can see that the 4-liter container has a lower price per gallon ($2.21/gallon) compared to the gallon of milk ($2.30/gallon).
Therefore, the 4-liter container of milk is the better buy because you get more milk for your money.
To determine which is the better buy between a gallon of milk and a 4-liter container of milk, we need to compare the prices per unit volume.
First, let's convert 4 liters to gallons. Since 1 gallon is equal to approximately 3.79 liters, we can divide 4 liters by 3.79 to get the equivalent amount in gallons. This gives us 4/3.79 ≈ 1.055 gallons.
Now, we can compare the prices:
- Gallon of milk: $2.30 for 1 gallon.
- 4-liter container of milk: $2.30 for approximately 1.055 gallons.
By comparing the prices per unit volume, we can see that the prices are the same for both options ($2.30). Therefore, the better buy is subjective and depends on the desired quantity of milk you need. If you need exactly 1 gallon, then buying just a gallon is more appropriate. But if you need more than 1 gallon, buying the 4-liter container is a better choice economically.
Remember, always compare prices per unit to determine the better buy.
