Quizplus · Accepted Answer

To find the range of sale price of gasoline per gallon, we need to find the lowest and highest price per gallon in the given data.

To find the lowest price per gallon, we divide the total cost of the highest gallon purchase by the number of gallons:

$\frac{44.40}{15} \approx 2.96$

To find the highest price per gallon, we divide the total cost of the lowest gallon purchase by the number of gallons:

$\frac{23.36}{8} \approx 2.92$

Therefore, the range of sale price of gasoline per gallon is approximately $\boxed{	ext{(C) }0.69}$, or $2.96-2.92$.
