Solving the problem mentally, with the "80% more pennies than nickels" I would say for every 5 nickels there are 9 pennies.

Then each group of 5 nickels and 9 pennies has a value of 34 cents.

The total $22.10, divided by 34 cents, gives 65 groups.

Finally, since each group contains 5 nickels, the number of nickels is 65*5 = 325.

Formally....

Let x = number of nickels
Then 1.8x = number of pennies

The total value of the nickels at 5 cents each and the pennies at 1 cent each is $22.10, or 2210 cents:

ANSWER: 325 nickels
