Answer:

  • 34 quarters and 24 dimes

---------------------------------------

Let the number of quarters be x, then the number of dimes is x - 10.

We know that quarter is $0.25 and dime is $0.10.

The total amount is $10.90.

Set up equation and solve for x:

  • 0.25x + 0.1(x - 10) = 10.9
  • 0.25x + 0.1x - 1 = 10.9
  • 0.35x = 11.9
  • x = 11.9/0.35
  • x = 34

Najee has 34 quarters and 34 - 10 = 24 dimes.
