A tub of water is emptied at a rate of 3 gallons per minute. The equation y β12 = β3(x β 1) models the amount of water remaining, where x is time (in minutes) and y is the amount of water left (in gallons). Analyze the work shown below to determine the initial amount of water.
1. Solve for the y-variable.
y β 12 = β3(x β 1)
y β 12 = β3x + 3
y = β3x +15
2. Write the equation using function notation.
f(x) = β3x +15
The tub started wth how much water?
