// // Write a function that calculates the amount of money a person would earn over // a period of years if his or her salary is one penny the first day, two pennies // the second day, and continues to double each day. The program should ask the // user for the number of years and call the function which will return the total // money earned in dollars and cents, not pennies. Assume there are 365 days // in a year. // function totalEarned (years) { // Insert your code between here and the next comment block. Do not alter // // any code in any other part of this file. // Insert your code between here and the previous comment block. // any code in any other part of this file. Do not alter // // var years = parseInt(prompt('How many years will you work for pennies a day? ')); var totalDollarsEarned = totalEarned (years); alert('Over a total of ' + years + ', you will have earned $' + totalDollarsEarned);
