Any way to simplify this code?

Question

New to javascript! This works, but I have a lot more to do, and it would be great if there was a cleaner way to do this.. open to using jquery if neccesary :)

You can use the following code to get the backers total.

function apply(){
    var answer = getBackers();
    document.getElementById("backer-prediction-answer").value = answer;
}

function getBackers()
{
    var baseName = "backer-prediction-";
    var elementId = "";
    var backers = 0;
    for(var i = 1; i < 20; i++)
    {
        elementId = baseName + i;
        backers = backers + getElementValue(elementId);
    }

    return backers;
}

function getElementValue(elementId)
{
    var value = document.getElementById("backer-prediction-1").value;
    return parseInt(value, 10);
}
