a bike shop charges a fee for renting a bike, depending upon how long it is used. riders who bring their own helmet are instead charged a discounted fee. the graph shows how the fees are related. how are the discounted fees related to the rental fees? each discounted fee is $? than the rental fee.
Answer
Explanation:
Step1: Select two - corresponding points
Let's take the points (10, 5) and (20, 15) for rental fees and their corresponding discounted - fee points.
Step2: Calculate the difference
For the rental fee of $10$, the discounted fee is $5$; for the rental fee of $20$, the discounted fee is $15$. The difference between the rental fee and the discounted fee for each pair is $5$. For example, when the rental fee $x = 10$, the difference $10 - 5=5$; when $x = 20$, $20 - 15 = 5$.
