ACTIVITY 2
Jonathan uses the following recipe to make chocolate muffins:
\begin{tabular}{|ll|}
\hline\( \frac{2}{3} \) cup of baking cocoa & \( 1 \frac{1}{3} \) cups of milk \\
2 large eggs & \( \frac{1}{3} \) cup of sunflower oil \\
2 cups of flour & 1 teaspoon of vanilla essence \\
\( \frac{1}{2} \) cup of sugar & \( \frac{1}{2} \) teaspoon of salt \\
2 teaspoons of baking soda & \\
\hline
\end{tabular}
2.1 Calculate how much baking soda Jonathan will use. Give your answer in me.
2.2 Calculate the amount of vanilla essence Jonathan will use in this recipe. Give your answer in \( \mathrm{m} \ell \).
(2)
2.3 Jonathan does not own measuring cups but he does own a measuring jug calibrated in \( \mathrm{m} \ell \).
Determine how many \( \mathrm{m} \ell \) of flour he needs.
\[
(1 \operatorname{cup}=250 \mathrm{~m} \ell)
\]
2.4 Jonathan buys a \( 100 \mathrm{~m} \ell \) bottle of vanilla essence.
Determine how many times he will be able to use the same bottle, if he bakes the same amount of muffins each time.

2.5 The recipe above is used to make 30 muffins. Calculate how many cups of flour Jonathan will need to make 45 muffins.
