Where we analyse a linear function, we must consider variations of each variable.
Also, linear functions variate according to its constant ratio of change, which is defined as
Which is the variation of the vertical value, regarding x-values.
So, if we want to show this variation, we must include a colum , which shows the variation we need, because it's the dependent value, then we can analyse the variation of the function for a certain x-interval.

Amount paid by Renee = $320
Amount paid by Susan = $280
Step-by-step explanation:
Here, the given question is INCOMPLETE.
Renee, Susan and Martha will share the cost to rent a vacation house for a week. Renee will pay 40% of the cost. Susan will pay 0.35 of the cost. Martha will pay the remainder of the cost. If the cost to rent the vacation house is $800, how much will each person pay?
Here, the total cost of the vacation = $800.
Renee pays 40% of the cost.
Calculating 40% of $800, we get:
So, Renee pays a total of $320 in the cost of vacation. ... (1)
Susan pays 0.35 = 35 % of the cost.
Calculating 35% of $800, we get:
So, Susan pays a total of $280 in the cost of vacation. ... (2)
Now, The amount paid by { Renee + Susan + Martha} = $800
⇒ $320 + $280 + Amount paid by Martha = $800
⇒Amount paid by Martha = $800 - $600 = $200
Hence, Amount paid by Martha = $200
Amount paid by Renee = $320
Amount paid by Susan = $280
