Wafer filling weight

The packaging of Horalka says, "A wafer with peanut cream filling (72%) in cocoa icing." If one wafer weighs 50 g, how many kilograms (kgs) fill one package containing 56 pieces of this wafer?

Final Answer:

x =  2.016 kg

Step-by-step explanation:

$$\begin{gathered} m_1=50\text{g}\to \text{kg}=50:1000\text{kg}=0.05\text{kg} \\ n=56 \\ q=72\%=\frac{72}{100}=\frac{18}{25}=0.72 \\ x=m_1\cdot n\cdot q=0.05\cdot 56\cdot 0.72=2.016\text{kg} \end{gathered}$$
