Xin is driving on a long road trip. She wrote an equation to represent how many gallons of gas she has left in her tank: [tex]g = 13 - 0.3h[/tex], where [tex]g[/tex] represents the number of gallons and [tex]h[/tex] represents time in hours.

What could the number 13 represent in the equation?

A. Initial amount of gas in the tank
B. Rate of gas consumption per hour
C. Total distance of the road trip
D. Time required to empty the tank

Answer :

Final answer:

The number 13 in Xin's equation corresponds to the initial amount of gas in the tank before she embarks on her trip.

Explanation:

The equation provided is g = 13 - 0.3h, for gas amount in gallons (g) over time in hours (h). The number 13 in this equation signifies the initial amount of gas in the tank. The reason being, this is the amount of gas Xin starts with before embarking on her trip, and as time proceeds, gas amount decreases at a rate of 0.3 gallons per hour. As such, the equation is demonstrating a linear relationship between the amount of gas left in the tank and the driving duration.
