A potted tree weighs 28 pounds. The pot weighs 4 pounds more than the tree. How much does the tree weigh without the pot? (Do not guess 24 because that is wrong.)

Respuesta :

The tree weighs 12 pounds. Since the pot weighs 4 more than the tree, the pot weighs 16 pounds. This checks because 12+16=28.

I think the answer is 7
