Jacob and Kerrie are trying to figure out how long they can live off their $84,670 savings if they spend $370 each month. They have each created an equation.

Jacob's Equation y = 84,670 + (370x)

Kerrie's Equation y = 84,670 - (370x)

Which person has the correct equation to model this linear relationship?

Kerrie's equation is incorrect, because their spending will increase the amount of their savings.

Kerrie's equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.

Jacob's equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.

Jacob's equation is incorrect, because their spending should be a fixed amount and should not be multiplied.
