Leah bought 3 boxes of birdseed. When she went to put them away, she discovered that she already had 5 boxes in the pantry. Her parrot eats 100 grams of seeds each week and her cockatiel eats 50 grams of seeds in a week. If each box of birdseed contains 225 grams, for how many weeks can she feed her birds without going back to the store? Let's think step by step and output the final answer after "####".

In a week, her birds eat a total of 100 grams + 50 grams = <<100+50=150>>150 grams of seed each week.
Leah has a total of 3 + 5 = <<3+5=8>>8 boxes of birdseed.
The boxes of birdseed contain a total of 8 * 225 grams = <<8*225=1800>>1800 grams.
This is enough birdseed to feed her pets for 1800 / 150 = <<1800/150=12>>12 weeks.
