I need to make a program that will take a number and multiply it by .15 so you know how much of a tip you need to leave.

I tried to put my bill input into a new variable in my function because I would get the tip total when I took the `number ()` out of my new variable, but doing this lead to nothing happening as JavaScript doesn't know it's a number

```
   <body>
    <input id="bill" placeholder ="How much was you meal?" />

    <button onclick ="tip()"> submit</button>

    <script> let bill = document.querySelector("#bill")

        function tip(){

            let yourTip = number( bill.value * .15)
            let total = yourTip * bill

            console.log ("Your tip  is $" + yourTip)
            console.log ("Your total after the tip is $" + total)
        }
    </script>
   </body>

```

I don't need to print it on the screen just in the console and the tip % does not need to change.
