Answer:
-15/2 exact form
-7.5 decimal form
-7 1/2 mixed number form
Step-by-step explanation:
Let's look at each answer separately:
A: we can't say that 1.3 cubic feet is about 1 cubic foot (there's a difference of 0.3 feet) and that 8 bags will give us a little less than 8 cubic feet - if we calculate 8*1.3 that'd give 10.4 cubic feet, which is much more than required
B: 2 bags will not give him a little less than 3 cubic feet (there's a difference of 0.6 feet) and so 6 bags will not give him a bit more than 8 cubic feet - if we calculate 1.3*6 we get 7.8 cubic feet, which is not enough
C: This answer is the most reasonable since the amount in 3 bags (3*1.3 = 3.9 cubic feet) is very close to 4 cubic feet, and so 6 bags would give him a little less than 8 cubic feet and thus he would require 7 bags
