Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Tom fills a 250 pound sandbag 80% full.  But the filling material he is using is 40% heavier than sand.  How much does the bag weigh?

### Response:
The bag full of sand would weigh 250 * 0.8 = <<250*0.8=200>>200 pounds
The filling material would make it 200 * 0.4 = <<200*0.4=80>>80 pounds heavier
So in total it would weigh 200 + 80 = <<200+80=280>>280 pounds
#### 280
