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:
61°C
Step-by-step explanation:
Newton's Law of cooling gives the temperature -time relationship has:
T (t) = 20 + 75 е⁻(t/50)-------------------------------------------------------- (1)
where Time is in minutes (min) & Temperature in degree Celsius (°C)
During the first half hour, t = 30 mins
Substituting into (1)
T = 20 + 75 е⁻(30/50)
= 20 + 75(0.5488)
= 20 + 41.16
= 61.16°C
≈ 61°C
