Question

Brandon was getting his garden ready. Soil came in bags of 1.3 cubic feet. He needed 8 cubic feet of soil.

Which best explains a reasonable number of bags of soil to buy?

A.
1.3 cubic feet is about 1 cubic foot, so 8 bags will give him a bit less than 8 cubic feet of soil. He should get 8 bags of soil.

B.
2 bags will give him about 3 cubic feet. So 6 bags will give him a bit more than 8 cubic feet. He should get 6 bags of soil.

C.
For every 3 bags of soil, he gets a bit less than 4 cubic feet. So 6 bags will give him a bit less than 8 cubic feet. He should get 7 bags of soil.
