I think You are forgetting about function that you learned in previous exercise.

No issue tho we will revise..

Suppose I made a function that prints multiplication of two numbers..

```
var multi = function (num1 , num2) {
console.log(num1 * num2);
}
```

Now we defined a function..

**Now how to use our function?**

To use our function.. *we call it*..

**How to call?**

We put name of function and put Exact same number of values inside it (inside the parentheses) separated by commas, that it needs.

As our example function needs two values!

`multi(2,3);`

It will print : `6`

Now your function is `orangeCost`

..

that takes price of orange and calculates price of 5 oranges.

```
var orangeCost = function(price) {
console.log(5.00 * 5 + price);
};
```

In console.log() you're making mistake.

Suppose I have to calculate price of 7 oranges..

I will write something like this..

`console.log(7 * price);`

But you have to write for 5 oranges?

Try that.

Now last part will be done by you...

As I explained how to create and use (call) a function..

now if a ornage costs 5 (like $5) then can you use your function to calculate price value of 5 oranges?
