Respuesta :

Answer:

The weight of Rachel is less than 40 Pounds.

The weight of Stephanie is less than 120 Pounds

Step-by-step explanation:

Sum of both both their weights is less than 160 pounds.

Let the weight of Rachel = k Pounds

⇒The weight of Stephanie = (3k) pounds

Now, according to the question:

k       +       3k   <   160

or, 4k < 160

⇒ k  < 160/ 4 = 40

or, k < 40

⇒ The weight of Rachel is less than 40 Pounds.

and The weight of Stephanie is less than (3 k = 3 x 40)   120 Pounds
