Answer:

$20 on each cat and $40 on each dog

Step-by-step explanation:

Call the amount spent on each, cat, x   and let the amount spent each dog = y = 2x

So we have the following constraints:

y = 2x   (1)

164(x) + 24y <= 4240  (2)  

Substituting  (1)  into 2 for y, we have

164x + 24(2x) <= 4240     simplify

212x <= 4240     divide both sides by 212

x<=  $20  on each cat

And  y  = 2(20)  = $40  on each dog

So she can spend $20 on each cat and $40 on each dog
