Question 1203794
<font color=black size=3>
Answers:
Golden Car Rental:   <font color=red>y = 35</font>
Classic Car Rental:  <font color=red>y = 0.80x+15</font>
where,
x = number of miles driven
y = total cost in dollars for 1 day only.



Explanation


Golden Car Rental charges $35 no matter how many miles have been driven. 
So we write <font color=red>y = 35</font> to represent this. The variable x isn't present. 
The cost (variable y) is always 35 here.


Classic Car Rental charges an up front fee of $15 for the day. Then an additional 80 cents (aka $0.80) per mile driven. 
We start with 15 and add on 0.80x to get 15 + 0.80x which is the same as 0.80x+15
This is how we arrive at <font color=red>y = 0.80x + 15</font>
