    273

    Step-by-step explanation:

    To start off, lets convert 9% into the decimal form so we can solve this problem easier. 9% would become 0.09 in its decimal form. Next, follow the math below ...

    (300) x (0.09) = 27

    Now, since Brian's cholesterol level was reduced, we know we have to subtract. We can finish the problem now ...

    300 - 27 = 273

    Brian's new cholesterol level is 273.
