Answer:
mutual mistake
Explanation:
A mutual mistake happens when all the parties involved in a contract (two or more) are mistaken or do not know the correct information about some specific material fact that is relevant to the contract. In this case, the contract can be rescinded because Harry believes that Ryan wants to buy his Cadillac, while Ryan believes Harry is selling his Porsche.  
Since both of them are mistaken and do not know relevant material facts regarding the contract, the contract can be terminated.

$2,134.62. 
There are approximately 52 weeks in a given year, meaning that there are 52/2, or 26, biweekly pay periods. Therefore, we divide the annual salary of $55,500 by 26 biweekly pay periods to get $2,134.62 for the biweekly paycheck. 
The formula is the annual amount divided by the number of periods. Here, there are 26 periods of biweekly (once every two weeks) paychecks.
