They would finance it through debt and equity, do it post IPO etc. There could be a merger instead of an acquisition. Currently if they cut their R&D by a bit and raise prices by 10% their more than healthy enough.
If they only raise prices by 10% it will cost them rides and drivers to Lyft / taxi etc. It's hard to say how much market share this would cost them, but you can't assume their numbers are going to be static with a price increase or they would have already increased prices.
