They have each created an equation.Davids Equation Amandas Equationy = 12,350 (240x) y = 12,350 + (240x)Which person has the correct equation to model this linear relationship? Amandas equation is correct, because their spending will be multiplied by the number of months and then added to their savings. Amandas equation is incorrect, because their spending will increase the amount of their savings. Davids equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings. Davids equation is incorrect, because their spending should be a fixed amount and should not be multiplied.You must check the box below prior to submitting your exam!
