There are 20! number of ways for everyone to do this so that at the end of the move, each seat is taken by exactly one person.

People are seated in a 2 by 10 rectangle grid. All 20 persons stand up from their seats and relocate to an orthogonally neighboring one upon the blowing of a whistle.

Now, we have to find the number of possible ways in which each seat is taken up by exactly one person after the move.

Doss [256]

Knowing that one dime has a 10 cent value and that a nickle has a 5 cent value, we can use multiplication or addition to find the answer.

5 x 10 = 50   5 dimes together are worth 50 cents.

2 x 5 = 10  2 nickles together are worth 10 cents.

50 + 10 = 60   5 dimes and 2 nickles are worth 60 cents when added together.

ANSWER: Aaron has 60 cents.
