Puzzle 2 - 3 lawyers and a missing dollar

-

 Solution to puzzle 1: 

        100 64 and 16.

Puzzle 2:

Three lawyers check into a hotel room and pay 30$ rent for the day - 10$ each per person. A waiter comes and tells them that they have won a discount offer and the total rent is only 25$ now. He returns 5$.  

The lawyers decide to keep 1$ each and give 2$ as tip to the waiter.

So the total was 9X3 +2 = 29.

They can’t understand where is the missing dollar.

Can you help them?

 The question was  What is wrong with this proof ? a=b multiply both the sides by a     --1 a2 = ab  add -b2 to both the side           --2 a2-b2 =ab-b2  factorizing                                --3 (a+b)(a-b) = b(a-b)  divide both the sides by (a-b)    ---4 a+b=b Substituting a with b,              ---5 2b = b Dividing both the sides by b    ---6 2 = 1   The problem is with step 4. When a is equal to b, a-b is zero. You can not divide numbers by zero because division is only defined for non-zero numbers.
