Step 1 :Let's denote the cost of the item as \(C\), which is given as \$19.
Step 2 :The sales tax rate is given as \(5.8\% \), which we can express as a decimal by dividing by 100, giving us \(0.058\).
Step 3 :We can calculate the sales tax charged on the purchase by multiplying the cost of the item by the sales tax rate, \(C \times 0.058\).
Step 4 :Substituting the given values, we get \(19 \times 0.058\), which equals \$1.1.
Step 5 :Final Answer: The sales tax charged on the purchase would be \(\boxed{1.1}\) dollars.
