Answer:Astrid needs 280 tons of wood
Step-by-step explanation:
Because:
1 ship requires 40 tons of wood=accomodates 300 sailors
We must:
2100, sailors needed to be accomodated
÷
300, sailors that can be accomodated by 1 ship that requires 40 tons of wood
=7 groups of 300 sailors that can be accomodated by 1 ship that requires 40 tons of wood.
So:
I ship that requires 40 tons of wood × the 7, groups = 280 tons of wood.
I hope this helps! Im sorry its too complicated.
Simplier:
2100 ÷ 300= 7
40 × 7= 280
