Answer:

The weight of the chocolate is


=84g

The percentage of cocoa is


\begin{gathered} =21\% \\ =(21)/(100) \end{gathered}

To figure out the grams of cocoa it contains, we will use the formula below


Amount_(cocoa)=Percentage_(cocoa)* amount_(chocolate)

By substituting the values, we will have


\begin{gathered} Amount_(cocoa)=Percentage_(cocoa*)amount_(chocolate) \\ Amount_(cocoa)=(21)/(100)*84g \\ Amount_(cocoa)=17.64g \\ Amount_(cocoa)\approx17.6g \end{gathered}

Hence,

The amount of cocoa to the nearest tenth is


\Rightarrow17.6g
