Answer:
let saved = amountSaved(12, 0.9, 0.06);
Explanation:
By presuming there is a JavaScript function amountSaved() that takes three input parameters, price, discountRate & salesTaxRate. To call the function, just simply write the function name, amountSaved 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 price, discountRate and salesTaxRate, 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 saved.
