Problem

HackerRank detailed problem description can be found here.

Inputs & Outputs

/**
 * Calculate and print rounded to the nearest integer result.
 * @param {number} meal_cost
 * @param {number} tip_percent
 * @param {number} tax_percent
 * @print {number} result
 * @return {undefined}
 */

Test Case

meal_cost = 15.00;
tip_percent = 20;
tax_percent = 13;

solve(15.00, 20, 13); // prints 20

JavaScript Solution

function solve(meal_cost, tip_percent, tax_percent) {
  let result = meal_cost + (meal_cost * tip_percent / 100) + (meal_cost * tax_percent / 100);
  console.log(Math.round(result));
}
