Chapter 4, Problem 6CR

To determine

To identify: the independent and dependent variables, then to represent the relation

using words, an equation and a graph.

Explanation of Solution

Given information:

The given table is as follows

  

The independent variable is number of chairs p.

And the dependent variable is paint left L

Representation using words:

The paint left is equal to difference of initial amount paint left and thirty times of number

of chairs .

Equation representation:

  $L=128-30p$

The graph of the equation is shown below:

  

Hence, the given table of data is represented in different ways.
