Answer:
she will be taking 3600 mgs. in 90 days
Step-by-step explanation:
if she is taking a 20 mgs. twice a day that will make it 40 mgs. a day. If she takes it for 90 days
you will multiply 90 by 40
so
90
x40
= 3600 mgs. in 90 days
Well, the numerator alone is
(5•4•3•2)! = 120 !
and the denominator alone is
5!= 120 .
So the value of the whole fraction is
119 !
