Total price of (AAPL option strike price + option cost) decreases with strike price. Why?
On July 20, when you posted this question, AAPL was trading almost at 115.  The market charges an extra premium for buying an option that is in the money (or on the money like this case) over one that is out of the money.  In order for the 130 Call to be worth something the market has to go up 15 points. Otherwise you lose 100% of your premium. On the other hand with the 115 every point that the market goes up means that you recover some of that premium. It is much more likely that you recover part of your premium with the 115 than with the 130.  With the higher probability of losing part of the premium, the sellers are going to be reluctant to write the option unless they receive larger compensation.
