I'll give this one a shot basically when you sell the put at 1.75 with the stock at .75 you are even there is no time value there. The 2.50 put is 1.75 in the money. The buyer of the put is betting it goes down more say it goes to .50 at this point the put he bought would be worth 2.00. If the stock goes up from this point say to 1.50 then the put would be worth 1.00 and you have a .75 gain at expiration.
The way you lose here is if the stock goes down to say .25 the buyer of the put gets to put the 10 puts or 1000 shares to you at 2.50 making 2.25 on the put he bought for 1.75 or .50. What you want is for the stock to go up to make the put value less. So in Dec if the stock closes at 2.50 or above you would keep the full credit. You can break down the gains from there. If it closes at 2.00 you make 1.25 the put is still worth .50. The thing about buying the put is at expiration the buyer gets to put the stock to you at the strike price. So make sure you have enough money to cover another 1000 shares if it closes below 2.50
