The answer to your questions are:
15.- 45 mg
16.- 25 kg
17.- 185 pounds
18.- 6 mg
Step-by-step explanation:
D = (a M) / (a + 12)
15.-
a = 4 years
M = 180
D = (4 x 180) / (4 + 12) = 720 / 16
D = 45 mg
16.- 1 pound --------------- 0.4535 kg
55 pounds ------------ x
x = 55 x 0.4535 / 1
x = 24.94 ≈25 kg
17.- 1 pound --------------- 0.4535 kg
x --------------- 84.09 kg
x = 84.09x 1 /0.4535
x = 185.42 pounds
18.- M = 18 mg what is 1/3 of the adult dose?
M = 18/3 = 6 mg
