Let c = cat food/medication cost
Let 2c = dog food/medication cost (because dog food/medication costs twice as much as cat food/medication)

Set up your formula based on the number of cats and dogs:
144c + 25(2c) = $4,268
144c + 50c = $4,268
194c = $4,268
c = $22
The cost per cat is $22. The cost per dog is twice that much or $44.

Let x be the amount it costs for a cat.
We know that a dog costs 2x

Given 144 cats and 25 dogs we get

144x+(2*25x)=4268

144x + 50x = 4268

194x = 4268

x = 4268/194 = 22

Therefore since each dog costs 2x we get $44 per dog.

okay if x is what you spend on cats then 2x is what you spend on dogs.

now we can set up an equation....

144x + 25(2x) = 4268

144x + 50x = 4268

194x =4268

x=22

So she can spend $22 on each cat. This means she will spend $44 on each dog.

d = 2c

4268 = 144c +25d = 144*d/2 + 25d = 72d + 25d = 97d

d = 4268/97 = 44
