Answer:

34

Explanation:

Let x represent the number of nickels Abby has. Then the number of dimes is 61-x. The total value of the coins, in cents, is ...

5x +10(61-x) = 440

-5x +610 = 440 . . . . . simplify

x - 122 = -88 . . . . . . . .divide by -5

x = 34 . . . . . . . . . . . . add 122

Abby has 34 nickels in her collection of coins.
