Upgrading a shop?

[hyperflutterby]

How much does it cost to upgrade a shop? I have a size 30 shop and am looking at joining a mall. I know it will cost 6k for one upgrade, but does anyone know how much it increases per upgrade so I can work out an equation for how much I'm about to spend?

I'm pretty sure it increases by 200 Neopoints per upgrade. My shop size is 50 and it takes 10k to upgrade.

I think it's an additional 200np per upgrade, but I could be wrong...

Thanks, now the hard part will be making a simple equation of that. If I come up with a really easy one I'll post it.

Edit: This is the best I could do:

X * N + (200 + 400 + 600...(200 * (N - 1)) = amount you will spend

(I think that is proper annotation for when you continue the 200 series N - 1 times)


X = the amount you start spending at (in my case 6000)

N = the number of times you upgrade

It is a pretty complicated equation, but it is the best I can come up with.

I would recommend against upgrading your shop just now, however -- with shops disappearing and (mostly) reappearing, it seems likely your expensive upgrade could vanish as the shop is restored to a former version.

I agree with hiddenneggs, you should wait a few days before updating your shop, neo is kind of glitchy right now.

id say about 200nps each time

Well I upgraded it yesterday without a problem. My shop was one of those that disappeared over the weekend because it was transfered to the new servers, but I did it after it came back.

200NP per shop size.

If you want a mathematical formula:

C = Cost to upgrade in Neopets
S = Current Shop Size

C = 200S
