E.
$x#c+$y#d=6

d=?

Each statement by itself is not suff.

1&2 together:
0.3c +0.4d=6
or
3c+4d=60

The above implies more than 1 potential value for d:
E.g. d=3, c=16 or d=6, c=12
Hence, E.

From stmnt 1 it's possible to figure out the price per cupcake, but that's not enough.
stmnt2 - just the sum of prices.
Combining does not help.
