We are given:
(1) 5n + 10d = 385; and
(2) n + d = 54.
From this, we may conclude:
(3) n + 2d = 77; {divide (1) by 5}
(4) d = 23; and {subtract (2) from (3)}
(5) n = 31. {subtract (4) from (2)}
Thus, there are 31 nickels, which answers your question.
Checking: we may see that 31 nickels make $1.55; and 23 dimes make $2.30. Thus, their total value is $3.85, and the total number of coins is 54, as you have specified.
