What is the difference between a relation and a function?
A relation is simply a set of ordered pairs that shows a connection between elements of two sets, while a function is a specific type of relation where each input value is associated with only one unique output value.

A car rental company charges a flat fee of $30 per day to rent a car, plus an additional $0.15 per mile driven. Let c represent the total cost (in dollars) to rent the car for x miles driven.
C=30+0.15x
$37.50.

The same car rental company begins to charge a different flat fee plus a per-mile cost for renting a car. The total cost C (in dollars) of renting the car for d days and driving m miles is modeled by the function:
C=40d+0.25m
If your friend rents the car for 5 days but drives only 100 miles, who pays more? By how much?
How much would it cost to rent the car for 3 days and drive 200 miles?
If you want to spend exactly $200, write an equation relating d and m.
If you drive no miles, how many days can you afford with $200?
Your friend pays $55 more (2,000 points)
$170 (1,000)
40d+0.25m=200 (1,000)
You can afford the car for 5 days if you don’t drive any miles. (1,000)
Solve for x.
(2x - 3) / 4 - 2(x + 1) = 3x - 5
X=1/2
