Step-by-step explanation:

We are given: dosage = 35 mg/kg

: mass of a child = 29 kg

: mass per capsule = 250mg/capsule

We first determine the number of capsules per kg:


\begin{gathered} capsules\text{ per kg = }\frac{dosage}{mass\text{ per capsule}} \\ \\ \text{ = }(35)/(250) \\ \\ \text{ = 0.14 capsule/kg} \end{gathered}

We then find the number of capsules for the child with the given mass:


\begin{gathered} no\text{ of capsules = caspsules per kg }* mass\text{ of a child} \\ \\ \text{ = 0.14}*29 \\ \\ \text{ = 4.06 capsules }\approx4\text{ capsules} \end{gathered}

Answer:

The child must receive 4 capsules.
