~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Let d be the number of dimes Darrel has.
Then the number of quarters is 28-d.

The "value" equation is

10*d + 25(28-d) = 460.

Simplify and solve it.

10d + 700 - 25d = 460,

-15d = 460-700,

-15d = -240,

d =  = 16.

Answer. 16 dimes and 28-16 = 12 quarters.
