Two sixth grade science classes are making salt water solutions. The first class (Class A) is using a ratio of three parts salt to five parts water. The other class (Class B) is using a ratio of two parts salt to four parts water. Using your coordinate plane, compare the two solutions. Which solution is saltier? Explain your answer.

Respuesta :

Answer:

Solution A: y = 0.6 x

 Solution B:  y = 0.5 x

From the above equations we can say that Solution A is saltier because  it has more salt per part of water.

Step-by-step explanation:

Let the amount of a part for salt be y.

Let the amount of a part of water be x.

Therefore for Class A we can say that

[tex]\frac{y}{x} = \frac{3}{5} \Rightarrow y = \frac{3}{5} x = 0.6x[/tex]

and also for Class B we can say that

[tex]\frac{y}{x} = \frac{2}{4} = \frac{1}{2} \Rightarrow y = 0.5x[/tex]

Solution A: y = 0.6 x

 Solution B:  y = 0.5 x

From the above equations we can say that Solution A is saltier because  it has more salt per part of water.
