    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.

    They spend 370 each month, so the total spent will be 370 times the #months THey start with 84670 Money at any time in months will be the beginning amount, minus, the total spent y = 84670 - 370*x y= remaining money , x = number of months

    A step further, the time they can live off that initial savings amount will be the number of months X, when the savings Y becomes Zero Dollars
