"The price will not increase twofold."

Translation: Harganya tidak akan naik dua kali lipat.

[BlakeLongm]

Is kali required? I'm pretty sure I've heard people say this without kali.

The word "two fold" literally means "dua lipat". But if u're talking about price, you have to use "kali" or "Times". It's like saying"the price is two times" higher
