Brian has reduced his cholesterol level by 9% after his last check up. If his original level was 300, what is his cholesterol level now?

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.
