The amount of sugar
in the starting solution contributes to a 36% concentration, so we have

units of sugar in the solution.
Into this solution, Sharon wants to pour
liters of water to obtain a smaller concentration of sugar in the overall solution:

So Sharon needs to add
liters of water to the solution to get the desired concentration.

Answer:
The youngest child will receive $2000
Step-by-step explanation:
A father decided to give 25% of his monthly income to his three children as their monthly allowance.
The eldest child got 45% of the allowance and the youngest got 20%. This means that the second child got:
100 - (45 + 20) = 100 - 65 = 35%
The second child received $3500.
Let the 25% of his monthly income be x.
Hence:
35% of x = 3500
=> 

x = $10000
The amount the man shared among his children is $10000.
Hence, the youngest child (20%) will receive:
20% of $10000

= $2000
The youngest child will receive $2000.
Answer:
One solution
Step-by-step explanation:
The blue line is a tangent line to the parabola, and because tangent lines only touch another line at one point, there must only be one solution to the system of equations.
