Answer:
8/23 cups of water for each plant. (Approx. 0.35 cups for each plant)
(I do hope this is correct)
Step-by-step explanation:
Since Lynn only filled half of her watering can full, it is now holding 8 cups pf water, since 16/2=8. Then, if she water each of her 23 plants equally, so each plan will supposedly get 8/23 cups of water.
