Eff needs to buy food and medication for six cats and one dog. the cost of food and medication for a cat is $5 less than two-thirds of the cost of food and medication for a dog.
if jeff spends a total of $195, the amount he spent on food and medication for the dog is

say the food and med cost for a dog is x

food and med cost for a cat would be 2/3x-5

so we can assume:

6(2/3x-5) + x = 195

4x - 30 +x     =195

5x - 30          =195

5x                  =195

therefore x, the food and med cost for the dog is 195/5 = 39$

i think that's right

correct answer:

i^31 = -i
