Six cells phones weigh 46.2 ounces. fourteen cell phones weigh 107.8 ounces. does this represent a proportional relationship? explain. if so state the constant of proportionality

The answer to your question is yes, there is a proportional relationship

Step-by-step explanation:

Data

6 cell phones weight 46.2 ounces

14 cell phones weight 107.8 ounces

Process

1.- Divide the weight by their respective number of cell phones

    a)    46.2 / 6 = 7.7

    b)   107.8 / 6 = 7.7

2.- Conclude. It is a direct proportion because the result of both divisions is equal. That means that if the number of cell phones increases, the weight will be higher.

  The constant of proportionality is 7.7.  

3.- Equation for the weight of any number of cell phones

           Weight = 7.7 x number of cell phones
