Answer:
No, they do not.
Explanation:
We can solve this problem by using two equations to represent how much the weavers charge for their blankets and sweaters.
Weaver One: 4b+6s=150
Weaver Two: 8b+12s=400
Let b represent the blankets.
Let s represent the sweaters.
If the weavers charge the same for their blankets and sweaters, the cost should be proportional.
4b÷8b=0.5
6s÷12s=0.5
150÷400=0.375
If the costs were proportional, all of the quotients should've been equal. Since 0.375≠0.5, this means that the weavers do not charge the same amount for blankets and sweaters.
