Final answer:

The amount of gas in the tank after x minutes of pumping gas can be represented by the equation y = 36x + 25.

Step-by-step explanation:

The amount of gas in the tank after x minutes of pumping gas can be represented by the equation y = 36x + 25. In this equation, y stands for the amount of gas in the tank (in gallons) and x represents the number of minutes. The slope of the equation is 36, which indicates that for every minute, 36 gallons of gas are being added to the tank. The y-intercept of the equation is 25, which represents the initial amount of gas in the tank when Lauren started pumping gas.

From the problem, the initial amount of gas in the tank is 25 gallons.

The pump is filling the tank at a rate of 36 gallons per minute.

We can express this as :


y=25+36x

where y is the amount of gas after x minutes.

25 is the initial amount of gas

36 is the rate

and

x is the time in minutes.

Rewriting the equation in slope-intercept form : y = mx + b

The answer is

y = 36x + 25
