Shen's

Shen's chocolate bar is 54% cocoa. If the weight of the chocolate bar is 54 grams, how many grams of cocoa does it contain? Round your answer to the nearest tenth.

Correct answer:

c =  29.2 g

Step-by-step explanation:

$$\begin{gathered} p=54\mathrm{\%}={\displaystyle \frac{54}{100}}=0.54 \\ m=54\text{ g } \\ c=p\cdot m=0.54\cdot 54=29.2\text{ g} \end{gathered}$$
