How to properly end a javascript statement?

Help....Javascript Program?

• A person invests $1,000 in a saving account yielding 5% interest. Assuming that all interest is left on deposit, calculate and display the amount of money in the account at the end of each year for 10 years. Use the following formula for determining these amounts: a = p(1 + r)n where p is the principal (original) amount invested, r is the annual interest rate, n is the number of years and a is the amount on deposit at the end of the nth year. Hint: JavaScript does not include an exponentiation operator. You can use the Math object's pow method for this purpose. Math.pow(x,y) calculates the value of x raised to the yth power. Method Math.pow takes two numbers as arguments and returns the result. Therefore, the statement for the formula may be: amount = principal * Math.pow(1.0 + rate, year); Unlike many other programming languages, JavaScript does not provide numeric formatting capabilities that allow you to precisely control the display format of a number. You can use the expression Math.round(amount * 100)/100 to format your numbers. This expression multiplies the current value of amount by 100 to convert the value from dollars to cents, then uses the Math object's round method to round the value to the closest integer. The result is then divided by 100, to produce a dollar value that has a maximum of 2 digits to the right of the decimal point.

• Answer:

  function calculate_amount(start_amount, interest_rate, years_passed) { var end_amount = start_amount * Math.pow(1.0 + interest_rate, years_passed); return Math.round(end_amount * 100)/100; } function print_amounts(start_amount, interest_rate, number_of_years) { for(var i = 1; i <= number_of_years; i++) { document.write("Year "+i+") "+ calculate_amount(start_amount, interest_rate, i)+"\n"); } } //an example with the initial amount being £1000 print_amounts(1000, 0.05, 10);
