Answer:
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.
