gallons of gas in her car. If the fuel efficiency of her car is

23

miles per gallon, how many miles can Nadine drive before running out of gas?

Calculate total miles: Calculate the total number of miles Nadine can drive by multiplying the amount of gas by the fuel efficiency. $\newline$ Total miles $= \text{Gallons of gas} \times \text{Fuel efficiency}$ $\newline$ Total miles $= 4 \text{ gallons} \times 23 \text{ miles per gallon}$
Perform multiplication: Perform the multiplication to find the total number of miles. $\newline$ Total miles = $4 \times 23$ $\newline$ Total miles = $92$ miles
