    The equation that models this situation is y = 5 – 0.3x and the temperature at 8:00 pm is 2.6

    How to determine the equation?

    The given parameters are
    Initial = 5
    Rate = 0.3 decrease
    The equation that models this situation is
    y = Initial – rate * x
    So, we have
    y = 5 – 0.3x
    The temperature at 8:00 pm is when x = 8
    So, we have
    y = 5 – 0.3 * 8
    Evaluate
    y = 2.6
    Hence, the temperature at 8:00 pm is 2.6
