A. 4.76 milligrams
B. 47.72 milligrams
C. 476 milligrams
D. 4.772 grams
15 mg/kg/day x 7 days = 105mg/kg
45.45 kg = 100 lb
1000mg = 1 g
105mg/kg x 45.45 lb = 4772.25mg or 4.772 g

Even taking it to two digits is bizarre.
Read WWD's answer again, and take it to heart. Your homework problems don't echo the real world, but you WILL have need of those math skills in direct to not kill race.
