Look for variables for cost of 1 dog and cost for 1 cat.

c and d, for cost of cat and of dog.

164c%2B24d=4240 accounts for the cost for the week.

Accounting for described cost differences, d=2c.


SIMPLE SUBSTITUTION
164c%2B24%2A2c=4240
164c%2B48c=4240
213c=4240
c=4240%2F212
c=20

d=40%2AdollarsPerDog
