Post amount must be in increments of 50 PHP

Question

i collect data using GET.

product=shoes&amount=30

so i collect the data

$amount = $_GET['amount'];

How do i echo out a message if the amount is not in increments of 10, so for example if amount was 25, i want to echo out saying "Amount needs to be in increments of 10". I have no code examples as i have tried to google this and can't find anything and i don't know where to even begin.

So i have not tried anything.
