Answer: Denny will spend 0.45 in bird seeds.
Step-by-step explanation:
1. you multiply $0.18 by 2 since you have 2 ounces.
this will give you $0.36
2. Then you will divide .18 by 2 since you only want to know what half of an ounce cost. This will give you $0.09
3. lastly you will add both of your results which will end up giving you $0.45
