Wyatt has 6 nickels and 5 dimes.

Given that Wyatt has X nickels and Y dimes, and he has no more than 11 coins worth no less than $ 0.80 combined, to determine one possible solution the following calculation must be performed:

  • 11 x 0.10 = 1.10
  • 1.10 - 0.80 = 0.30
  • 0.30 / 0.05 = 6
  • 11 - 6 = 5
  • 6 x 0.05 + 5 x 0.10 = 0.80

Therefore, Wyatt has 6 nickels and 5 dimes.
