Use reasoning to answer the following question.
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?

280
The bag full of sand would weigh 250 *.

8 = 200 pounds.

The filling material would make it 200 *.

4 = 80 pounds heavier.

So it weighs 200 + 80 = 280 pounds.

.

The final answer: 280
