    Answer:

    Hi there!

    Your answer is;

    There are 50 bacteria after 3 hours

    Step-by-step explanation:

    After three hours, with a rate of 20% an hour, 60% should have died

    20% of 125 is?

    100% is 125

    /100

    1% is 1.25

    ×60

    60% is 75

    125-75= 50

    Hope this helps
