Question

A sporting goods store displays the following sale sign. What is the constant of proportionality? Regular Price (dollars) 25 Sale Price (dollars) 18.75 150 112.50 168.75 Your answer

Answer 1

Refering to sales price in the store, the constant of proportionality will be the quotient between each sales price and its corresponding regular price

$\frac{18.75}{25}=\frac{112.5}{150}=\frac{168.75}{225}=0.75$

The constant of proportionality is 0.75
