ANSWER


B.\text{ }P=(D)/(5)

Step-by-step explanation

We want to find the equation that represents the relationship.

The relationship between the number of packages and the cost of sending the packages is a proportional relationship.

This implies that the equation for this relationship can be written as:


P=k*D

where P = number of packages

D = cost of sending packages

k = constant of proportionality

To find the value of k, let us substitute the values of P and D from the question.

We have that P = 5 and D = $25. Therefore:


\begin{gathered} 5=k*25 \\ \\ k=(5)/(25) \\ \\ k=(1)/(5) \end{gathered}

Therefore, the equation that represents the relationship is:


\begin{gathered} P=(1)/(5)*D \\ \\ P=(D)/(5) \end{gathered}

The correct option is option B.
