The pharmacist has a 3.6 L bottle of cough syrup. If she fills a bottle that is 1,500 ml, how many ml of cough syrup does the pharmacist have left? (1 L = 1,000 ml)

Question

21 ml
150 ml
1,360 ml
2,100 ml

Answer 1

The pharmacist has a total of 3.6 L * 1,000 ml/L = <<3.6*1000=3600>>3600 ml of cough syrup.
After filling a bottle with 1,500 ml, the pharmacist has 3600 ml - 1500 ml = <<3600-1500=2100>>2100 ml of cough syrup left. Answer: \boxed{2,100 \text{ ml}}.
