For the bunny hill here (which is all you need on your first day) it's $35. Rental gear is $35 for the day. (Board, boots, helmet if you want it)
You need snow pants, jacket, gloves, hat, scarf. Dress in layers. Cheap snow gear from Walmart/target is fine. Or get it second hand. Or borrow it. I'm actually wearing rain pants. You also need goggles. I'd buy a pair from amazon that isn't expensive but has good reviews. Maybe another $35.
Probably worth taking a beginner lesson if you don't have a friend who can instruct you. Here those range from $70 to $140 depending on the day or resort. Or just watch a bunch of YouTube videos.
