To add these two amounts together, we need to add the pounds and ounces separately.

First, let's add the pounds: 12 lb + 17 lb = 29 lb.

Next, let's add the ounces: 8 oz + 8 oz = 16 oz.

However, since there are 16 ounces in a pound, we can convert this into pounds. We divide 16 by 16, which gives us 1 lb.

So, the total ounces is 16 oz, which is equal to 1 lb, and we add this to the pounds.

Putting it all together, 29 lb + 1 lb = 30 lb.

Therefore, 12 lb 8 oz + 17 lb 8 oz is equal to 30 lb.
