Answer:
A
Step-by-step explanation:
First I converted the fractions into decimals to make it easier to solve.
2 1/2 —> 2.5
1 3/4 —> 1.75
Then I added the two decimals together.
2.5 + 1.75 = 4.25
Then I divided this number by 100 (the number of cups in one bag)
100/4.25=23.529
With this equation I know that one bag lasts 23 full days.
This is almost a month, and so it would not make sense for the answers to be B, C, or D.
Hope this helped

Answer:

Since the measurement can't be negative the correct answer for this case would be 
Step-by-step explanation:
Let's assume that the figure attached illustrate the situation.
For this case the we know that the original area given by:

And we know that the initial area is a half of the entire area in red
, so then:

And we know that the area for a rectangular pieces is the length multiplied by the width so we have this:

We multiply both terms using algebra and the distributive property and we got:

And we can rewrite the expression like this:

And we can solve this using the quadratic formula given by:

Where
if we replace we got:

And the two possible solutions are then:

Since the measurement can't be negative the correct answer for this case would be
