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

`(18.75)/(25)=(112.5)/(150)=(168.75)/(225)=0.75`

The constant of proportionality is 0.75
