Answer

$2,622,950$ nurses

Work Step by Step

Let $x$ be the number of registered nurses in $2008.$ The conditions of the problem translate to the equation \begin{array}{l}\require{cancel} x+0.22x=3,200,000 .\end{array} Using the properties of equality, the equation above is equivalent to \begin{array}{l}\require{cancel} 1.22x=3,200,000 \\ x=\dfrac{3,200,000}{1.22} \\ x=2622950.8196721311475409836065574 .\end{array} Hence, the number of nurses in $2008$ was $ 2,622,950 .$
