    If the scatter plot was made with weekly data (x axis in "weeks")

    y = 17.63 (5) + 27.52 = 115.67 (money saved)

    If the scatter plot was made with daily data (x axis in "days")

    y = 17.63 (5*7) + 27.52 = 644.57 (money saved)

    Step-by-step explanation:

    We just need to apply the equation found by Adan with his model and substitute depending on wether his plot was on days or weeks.
