Explanation / Answer

1) Given 1 gallon of milk costs $3.48

so $3.48/ 1gallon ,   and 1 $/ 0.287 gallon

2) Given 6.10 lb of meat sells for $4.95 / lb

cost of meat = weight of meat * converstion factor = 6.1 lb * $4.95 / lb = $ 30.195   Answer

3) doctor prescribes 100 mg of pediazole every six hours

pharmacy supplies solution containing 600 mg of pediazole per 5ml = 600mg /5 ml = 120mg/ml of pediazole

ml of solution to be taken = 100 mg / 120 mg/ml = 0.83 ml

so 0.83 ml of the solution given by pharmacy should be taken every 6 hours. Answer
