    Answer: Amy is incorrect. The answer is -5 points.

    Step-by-step explanation:

    From the question, we are informed that Amanda earned 20 points for winning a sprint in the first race but got -25 points in the second race.

    Based on the information above, Amanda’s total score now will be:

    = 20 + (-25)

    = 20 – 25

    = -5

    The answer is -5 points.

    Amy is wrong because (+) × (-) = (-)
