Answer:

5.445

Step-by-step explanation:

[tex]\bold{METHOD\ 1:}\\\\p\%=\dfrac{p}{100}\to16.5\%=\dfrac{16.5}{100}=\dfrac{16.5\cdot10}{100\cdot10}=\dfrac{165}{1000}=\dfrac{33}{200}\\\\16.5\%\ of\ 33=\dfrac{33}{200}\cdot33=\dfrac{1089}{200}=5.445[/tex]

[tex]\bold{METHOD\ 2:}\\\\\begin{array}{ccc}100\%&-&33\\\\16.5\%&-&x\end{array}\qquad\text{cross multiply}\\\\\\100x=(16.5)(33)\\\\100x=544.5\qquad\text{divide both sides by 100}\\\\x=\dfrac{544.5}{100}\\\\x=5.445[/tex]
