Chapter 8, Problem 23MCQ

To determine

To Check:Whether the proportional relationships exists between the two quantities.

Answer to Problem 23MCQ

The quantities are in proportional relationship

Explanation of Solution

Given:Determine whether the proportional relationships exists between the two quantities shown in each of the function indicated.

  

To determine if the quantities are proportional

Find $\frac{y}{x}$ for the points.

i.e.

Ratio of cost by number of people in the water park.

  $\begin{array}{l}\frac{y}{x}\\ \frac{36}{3}=12\\ \frac{48}{4}=12\\ \frac{60}{5}=12\end{array}$

Since the ratios are equal the quantities are in proportional relationship
