Question

Please break the program in to functions (make it modullar)

// Constant real taxRate = .0945
const taxRate = parseFloat(.0945);
//constant real tipRate = .2
const tipRate = parseFloat(.2);

//declare reaL foodCost, taxAmt, tipAmt, finalTotal
var foodCost
var taxAmt
var tipAmt
var finalTotal

// Display "Please enter your foodCost"
// Input foodCost

foodCost = prompt("Please enter your foodCost");
foodCost = parseFloat(foodCost);
taxAmt = foodCost * taxRate;
tipAmt = tipRate * (taxAmt + foodCost);
finalTotal = foodCost + taxAmt + tipAmt;

//Dispaly "the results"
//Display= ("The tax Amount is $ ", taxAmt)
//Display= ("The 20% tip is $ ", tipAmt)
//Display= ("The total cost is $ ", finalTotal)

alert("The tax amount is " + taxAmt.toFixed(2))
alert("The 20% tip is " + tipAmt.toFixed(2))
alert("The total cost is " + finalTotal.toFixed(2))

Explanation / Answer

function taxAmountCalculator(p1, p2) {

return p1 * p2; // The function returns the product of p1 and p2

}

function tipAmountCalculator(p1, p2, p3) {

return (p1 * (p2+p3)); // The function returns the product of p2 and p3 addition with p1

}

function finalAmount(p1, p2, p3) {

return p1 + p2+ p3; // The function returns the Additon of p1, p2 and p2

}

function displayResult(taxAmt, tipAmt, finalAmount){

alert("The tax amount is " + taxAmt.toFixed(2))

alert("The 20% tip is " + tipAmt.toFixed(2))

alert("The total cost is " + finalTotal.toFixed(2))

}

// Constant real taxRate = .0945

const taxRate = parseFloat(.0945);

//constant real tipRate = .2

const tipRate = parseFloat(.2);

//declare reaL foodCost, taxAmt, tipAmt, finalTotal

var foodCost

var taxAmt

var tipAmt

var finalTotal

// Display "Please enter your foodCost"

// Input foodCost

foodCost = prompt("Please enter your foodCost");

foodCost = parseFloat(foodCost);

taxAmt = taxAmountCalculator(foodCost , taxRate);

tipAmt = tipAmountCalculator(tipRate ,taxAmt ,foodCost);

finalTotal = finalAmount(foodCost , taxAmt , tipAmt);

//Dispaly "the results"

//Display= ("The tax Amount is $ ", taxAmt)

//Display= ("The 20% tip is $ ", tipAmt)

//Display= ("The total cost is $ ", finalTotal)

display_result(taxAmt, tipAmt, finalTotal)
