Question

Benadryl is used to treat itchy skin in dogs. The recommended dosage is 1 mg per pound. What mass of Benadryl, in milligrams, should be given to a dog that weighs 29.5 kg?

Answer 1

Answer:

65 mg

Explanation:

We are given the dosage per pound but have the weight of the dog in kilograms, thus we should convert the 29.5 kg to punds ( 1 pound = 0.454 kg):

29.5 kg  x 1 lb / 0.454 kg = 64.7 lbs

So now can answer our question:

( 1 mg / lb ) x 64.7 lb = 64.7

rounding to 65 mg
