• D. $2. 12/gal
•E. $4. 24/gal

Answer 1

To find the cost of gasoline per gallon when it costs $0.50 per liter, we need to perform the following calculations:

1. **Convert quarts to liters**: Since there are approximately 1.06 quarts in a liter, we can find out how many liters are in a gallon.
- Since there are 4 quarts in a gallon, the number of liters in a gallon can be calculated as:
\[
\text{liters per gallon} = \frac{4 \text{ quarts}}{1.06 \text{ quarts/liter}} \approx 3.7747 \text{ liters/gallon}
\]

2. **Calculate the cost per gallon**: Now that we know there are approximately 3.7747 liters in a gallon and gasoline costs $0.50 per liter, we can find the cost of gasoline per gallon:
\[
\text{cost per gallon} = \text{liters per gallon} \times \text{cost per liter}
\]
\[
\text{cost per gallon} = 3.7747 \text{ liters/gallon} \times 0.50 \text{ dollars/liter} \approx 1.88735 \text{ dollars/gallon}
\]

3. **Round the calculated cost**: Rounding $1.88735 to two decimal places gives $1.89.

So the cost of gasoline per gallon is approximately **$1.89/gal**.

The answer is **C. $1.89/gal**.
