To find the quantity of gasoline that Olivia bought in liters, you can use the conversion factor that 1 gallon is equal to 3.8 liters.
Olivia bought 8 gallons of gasoline, so you can calculate the total amount in liters as follows:
\[ \text{Total liters} = \text{gallons} \times \text{liters per gallon} \]
Substituting the values:
\[ \text{Total liters} = 8 , \text{gallons} \times 3.8 , \text{liters/gallon} \]
Now, perform the multiplication:
\[ \text{Total liters} = 8 \times 3.8 = 30.4 , \text{liters} \]
Thus, Olivia bought 30.4 liters of gasoline.
