Final answer:
To determine the amount of water to be consumed with a 1000mg dose of ibuprofen, a proportional calculation reveals that a person should drink 20 ounces of water.
Step-by-step explanation:
To determine how many ounces of water should be consumed with a 1000mg dose of ibuprofen based on the ratio provided, we'll use a simple proportional calculation. We know that for every 400mg of ibuprofen, it is recommended to drink 8 ounces of water. Therefore, we can set up the proportion:
400mg ibuprofen : 8 ounces water = 1000mg ibuprofen : x ounces water
To solve for x, we can cross-multiply and divide:
(400mg) * (x ounces) = (8 ounces) * (1000mg)
x = (8 ounces * 1000mg) / 400mg
x = 8000 / 400
x = 20 ounces
Thus, a person should drink 20 ounces of water with a 1000mg dose of ibuprofen.
