There are various ways/approaches that one can take to answer this question. The following is just one.
4 days x 24 hrs / day = 96 hours
1 dose q 6 hrs for 96 hrs = 16 doses total
3 btls x 60 mls = 180 mls
180 mls x 1 tsp / 4.93 mls = 36.5 tsps total
36.5 tsps / 16 doses = 2.3 tsps per dose
Answer would be 2 tsps should be taken for each dose.
