Answer:
Total tea bags in the box could be any of these: 71 , 57, 61, 47
Step-by-step explanation:
from the question given a tea bag can make either two or three cups of tea
A) Anastasia made 57 cups of tea
there are two possibilities is either she made 2 cups per bag or 3 cups par bag
i) when she makes two cups of tea per bag : number of teabag used = 57/2 = 28.5 ≈ 29 bags
ii) when she makes three cups per bag : number of teabags used = 57 / 3 = 19 bags
B) Elizabeth made 83 cups of tea
iii) if she makes two cups per bag = 83 / 2 = 41.5 ≈ 42
iv) if she makes three cups per bag = 83 / 3 = 27.66 ≈ 28
probable amount of teabags in the box
= i +iii , i + iv , ii + iii , ii + iv
= ( 29 + 42 ) , ( 29 +28 ), ( 19 + 42 ), ( 19 + 28 )
= 71 , 57, 61, 47
