Answer:
28 hours
Step-by-step explanation:
21/3 = 7
7x4=28
<span>Let x = amt of water evaporated :.05(50) = .08(50-x) 2.5 = 4 - .08x .08x = 4 - 2.5 .08x = 1.5 x = 18.75 lb of water evaporated : ; Check; amt of salt remains the same, only the percentage is different, right? .05(50) = .08(50-18.75) .05(50) = .08(31.25) 2.5 = 2.5</span>
In the question, there are two people with different percentage of drinking water from different quantities.
Taking the first case of Kylie we get that he drank 35% water of 400ml
Then
35% of 400 ml = (35/100) * 400 ml
= (35 * 4) ml
= 140 ml
So Kylie drank a total of 140 ml water.
Now taking the case of Eugenia we get that he drank 45% of 350 ml water.
Then
45% of 350 ml = (45/100) * 350
= 1575/10 ml
= 157.5 ml
So Eugenia drank 157.5 ml of water. Then we can conclude that Eugenia drank more water than Kylie.
