Answer:
A
Explanation:
First I converted the fractions into decimals to make it easier to solve.
2 1/2 โ> 2.5
1 3/4 โ> 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
