If the recommended adult dosage for a drug is D (in mg), then to determine the appropriate dosage c for a child of age a, pharmacists use the equation $c = 0.0417 D ( a + 1 )$ Suppose the dosage for an adult is 300 mg. Find the dosage for a newborn
A) 299 mg

For a newborn, age $a = 0$. Substituting $D = 300$ and $a = 0$ into the equation $c = 0.0417D(a + 1)$, we get $c = 0.0417 \times 300 \times (0 + 1) = 12.51$ mg, which is not listed among the options provided.

If the Recommended Adult Dosage for a Drug Is D c=0.0417D(a+1)c = 0.0417 D ( a + 1 )c=0.0417D(a+1)

If the Recommended Adult Dosage for a Drug Is D $c = 0.0417 D ( a + 1 )$
