    125-37.5= 87.5
    I think it’s the third option

    Answer:

    42.9%

    Step-by-step explanation:

    So you would use [ ((V2 – V1) / |V1|) * 100 ]

    V1 = 87.5 to V2 = 125

    = ((125 – 87.5) / |87.5|) * 100

    = (37.5 / 87.5) * 100

    = 0.428571 * 100

    = 42.8571% change

    = 42.8571% increase

    Then you round to 42.9!

    Hope it helps! 🙂
