Step-by-step explanation:
If x is the volume of pure water:
Initial + added = final
0.95 (840) + 0 (x) = 0.70 (840 + x)
798 = 588 + 0.70 x
x = 300
840 + x = 1140
You need to add 300 mL of pure water to obtain 1140 mL of the desired 70% solution.

Answer:
He can work a maximum of 2 8-hour days for the remainder of the week
Step-by-step explanation:
Firstly, from the question, we are made to know that the maximum work hours is 40 hours.
Now, we know that he has already worked 24 hours this week, the number of hours remains to work will be 40-24 = 16 hours
Now, given that his working hour is 8-hours per day, we want to know the number of days he has to work for the remainder of the week
Mathematically, that would be 16 hours divided by 8-hours days
That is 16/8 = 2
