NEED HELP MEDAL FAN

OpenStudy (k12girlohva):

Brian has reduced his cholesterol level by 10% by following a strict diet and regular exercise. If his original level was 200, what is his cholesterol level now? A. 220 B. 198 C. 20 D. 180

OpenStudy (k12girlohva):

I THINK ITS D

OpenStudy (anonymous):

20

OpenStudy (anonymous):

its C

OpenStudy (isaidavila):

200-10/100*200

OpenStudy (anonymous):

you have to multiply 200 by .10 which is equivalent to 10%

OpenStudy (k12girlohva):

its C?

OpenStudy (isaidavila):

Is not C is 180

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

explain

OpenStudy (k12girlohva):

Yea i thought it was D also

OpenStudy (anonymous):

oh sorry i misread that, i thought he had 10% left, it is 180

OpenStudy (anonymous):

i apologize

OpenStudy (isaidavila):

Because he loses 10% percent of the original weight, so he loses 20 Now his weight is 200-20=180

OpenStudy (mathmale):

It's important that you (k12) show your own work, to back up any answer choices that you make. What is 10% of 200 lb?

jhonyy9 (jhonyy9):

10% of 200 = 20 so than 200-20=180

OpenStudy (isaidavila):

Don't worry about that

OpenStudy (k12girlohva):

Tbh i actually wasnt sure of how to do this corectly i just thought it was 180 by looking at wat i had.
