Marcia dissolved 1 kg of salt in 3 litres of water.
Bobby dissolves 2 pounds of salt in 7 pints of water
2.11 pints = 1 litre
7 pints = 7/2.11
           = 3.32 litre
1 pound =0.45 kg
2 pound = o.45*2 kg
               = 0.9 kg
So we find that Bobby is dissolving 0.9kg of salt in 3.32 litre of water
Marcia is dissolving 1 kg of salt in 3 litres of water.
So it can be said that Marcia made a more concentrated salt solution.

Anyone mind helping!?
Ksju [112]

Answer:

B) 3\sqrt{3}

Step-by-step explanation:

First simplify the radical on the right.

\sqrt{75} is equal to \sqrt{25} *\sqrt{3} , because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.

Then we know \sqrt{25} is just equal to 25, which means the simplified version of \sqrt{75} is 5\sqrt{3}.

Then we can use this new representation to finish solving.

8\sqrt{3}-5\sqrt{3} =3\sqrt{3}, so the answer would be B
