Shopify basic price indication - shopify

Question

I try to make a basic price indication for my german Shopify store. In this line, I've tried to give out the basic price, which is: product.price / first variant value * 10 but I don't know how to get the value from that. Maybe someone can help me with this.
I hope my description is complete.
(there are 3 sets of variants but only the 1. is important so it has to be something like product options selector = 0 or something)
THX!
