amount x .25 x month + amount / month = result. I have tried but the result is always wrong.

```
Amount: <input id="amount" type="text" />
Month: <input id="month" type="text" />

<input type="submit" onclick="output();">

<p id="result"> </p>

<script>
    function output(){
        var amount = parseInt(document.getElementById('amount').value);
        var month = parseInt(document.getElementById('month').value);
        document.getElementById('result').innerHTML = amount * .25 * month + amount/month;
    }
</script>

```
