How many nickels are there in seventeen dollars?

The answer is:  " 340 " .   There are 340 nickels in 17 dollars.

Explanation:

There are 20 nickels in one dollar.

Since 1 dollar = $1.00 = 100 cents ; and:

          1 nickel = 5 cents


(5 cents)*x = 100 cents ; solve for "x" ;  x = the number of nickels in 1 dollar;

Divide each side of the equation by "5 cents" ;

[(5 cents)*x] / (5 cents) = (100 cents) / (5 cents) ;

to get: 

                  x  = 20 .

There are 20 nickels in one (1) dollar.

20 nickels * 17 dollars = number of nickels in 17 dollars.

  20 * 17 = 340 nickels in 17 dollars.

 The answer is:  " 340 " .   There are 340 nickels in 17 dollars.
