A. The concentration of the solution will increase because the water evporated; the leftover solution has the same amount of sugar and Kool-mix but with a smaller volume of water.

B. The concentration of the solution will decrease because the water evporated; the leftover solution has the same amount of sugar and Kool-mix but with a smaller volume of water.

C. The concentration will stay the same because as the water evaporates the sugar and Kool-aid mix also evaporate.

D. You would have to measure the concentration in a lab

A.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.
