Since supplies for each dog are twice what they are per cat, it's like she's feeding 164+48, or 212 cats. 4240/212=$20/cat. Since dogs are twice as much, her budget is $40/dog. ☺☺☺☺

c, expenses for 1 cat
d, expesnes for 1 dog
d=2c


Account for the budget of $4240.
164c%2B24d=4240


Substitute for d.
164c%2B24%2A2c=4240

164c%2B48c=4240
212c=4240
highlight%28c=20%29, expense for 1 cat.

highlight%28d=40%29-----for 1 dog
