Sometimes, there are double IP weekends in League of Legends.
How do IP boosts,per Win or over days, affect the won IP during that time?
Possible Scenarios (assuming a win without the weekend and boots gives X IP):
X * 4 : All bonuses stack additively (normal + double weekend + per win boost + der day boost = 4) and are multiplied afterwards
X * 6 : normal + double weekend counts as normal and per win boost + per day boost are multiplied afterwards = X * 2 * 3
So I don't know of any specifics related to Coop (as compared to PvP), but I do know that Riot recently changed their formula. If I understand the new formula correctly, there should be no difference between PvP and PvE IP/XP gains on a per game basis (obvious caps still apply).
Previously, the system was based around providing IP in comparison to the 20minute mark (also known as the surrender minimum time). As you played towards that mark you gained more IP/XP and after that mark, these gains rapidly diminished.
To help explain this, let's take the following sample:
I play a PvP against Grace Note and she beats me 25 minutes in. She gets about 115 IP (plus a bonus) for winning and I get about 65 for losing. Now, let's say we play again and again she wins, but this time it takes her 45 minutes to woop my butt. I would get 72 IP for hanging in longer, but she would only get 100IP!
Obviously the goal here was to penalize longer wins and shorter losses. Unfortunately, this encourages farming games, where teams agree to surrender at the 20 minute mark. So Riot changed that formula to a new one. Here's your TL;DR:
IP/XP scales with time
For those concerned about endless games, the formula is essentially linear up till the 55 minute mark. Additionally, both Winners and Losers scale up with time (meaning you're no longer penalized for a long win). There is also an extra flat bonus for playing the game which does not scale. Finally, they've also removed the bonus for non-leaver streaks (in preference to the new judgement system.

Post Script
For those unaware there are also difficulty scaling modifiers for Coop vs AI
These percentages represent how much of the standard reward is received:
- Summoner level 1-9: Beginner: 100% Intermediate: 100%
- Summoner level 11-19: Beginner: 75% Intermediate: 100%
- Summoner level 20-29: Beginner: 50% Intermediate: 100%
- Summoner level 30: Beginner: 25% Intermediate: 75%
No, the +150 bonus-of-the-day is not impacted by playing an AI game or a Custom Game instead of a PvP game. You need only make sure that you win the game, and you'll earn an un-changed +150 IP on top of however much (reduced) XP/IP you get normally.
It's actually not uncommon that some players will specifically do a relatively quick AI match just to secure that win, especially if you're having a bad day on the PvP end.
Best Answer
IP boosts work additively. Buying different boosts will stack (this does not work when buying the same boost).
For every boost, you earn the IP of the base IP you earned, whether it's a won match or a lost one. Of course the First Win of the Day boost (which cannot be enhanced and is fixed on 150 IP) will only get taken into account when you actually win a match, which is available after every 22 hours when consumed.
Formula: Base IP + any boost
Example: Base IP + IP boost + Weekend Bonus + First Win of the Day gives 80 + 80 + 80 + 150 IP = 390 IP from a single match.
