Hello everyone. I’m new to the Javascript language and wish to ask for some help please.  
I’ve been given a task but I’m unsure how to go about it. I managed to work out how long it’ll take but unsure how to add in the 1% increase.

A man puts £5800 into a bank account to buy a car. The bank account attracts interest of 4% a year.  
The price of the car is £6500. But the price goes up by 1% a year!  
Assuming that the man does not take out, or add any money, how many years before he can buy the car?  
And what would be the price of the car?

I think you want something along the lines of the following:

```javascript
let balance = 5800
let carPrice = 6500
let years = 0

for(; balance <= carPrice; years++) {
  balance += balance * 0.04
  carPrice += carPrice * 0.01
  console.log(years, balance, carPrice)
}

console.log(`end years ${ years }, end price ${ carPrice }`)

```

Thank you, sir. I wasn’t sure how to add in the 1% increase and also get the end result.
