4% of the 200 pills failed to retain full potency after 60 days.
In order to find this out, we just needed to find out which one has the same smallest fraction
25 / 35. Divided this by 5 and we will get 5/7 >>> smallest fraction
15/21 . Divided this by 3 and we also will get 5/7 >> smallest fraction
So the answer would be : B. 15/21
hope this helps
It would be two places to the right of 0 because -3+5=2
Supplier A: $188.6
Supplier B: $221.6
I hope I helped but I honestly have no idea if I did. Anyway sorry if I didn't. Good luck.
