Answer:
let saved = amountSaved(12, 0.9, 0.06);
Explanation:
By presuming there is a JavaScript function <em>amountSaved() </em>that takes three input parameters, <em>price</em>, <em>discountRate</em> & <em>salesTaxRate</em>. To call the function, just simply write the function name, <em>amountSaved</em> followed with a pair of parenthesis. Within the parenthesis, include three testing values, 12, 0.9, 0.06 as arguments. These argument values will be held by the three parameter <em>price</em>, <em>discountRate</em> and <em>salesTaxRate</em>, respectively.
The function will operate on the three input values and return the result to the main program where the returned result is assigned to a variable name <em>saved</em>.
