    Answer:  8000 points last week.

    Step-by-step explanation:

    If she has increased by 75% in a week to get 14000 points then  we can say that 175% times a number has to equal 14,000 , where the number of points she had last week.

    175% * x = 14000

    1.75x =14000     Divide both sides by 1.75

    x= 8000

    So she had 8000 points last week.

    Check:

    175% * 8000= 14000

    1.75 * 8000 = 14000

      14000 = 14000
