## Lets Compare!

**The table below shows the cost for every minute you talk for both deals.**

## Deal #1 The x represents the time(min) and the y represents cost(cents). | ## Deal #2 The x represents the time(min) and the y represents cost(cents). | ## A deals a deal! Buy one of the two deals, and get an antique phone absolutely free. |

## The Variables

## Calculate Youself

For deal 1 - y= 5x

For deal 2 - y= 4x+4

Substitute x with the amount of minutes that you talk for. The cost (y) varies directly with the x.

The formula for deal 1 is a direct variation since it has a variable cost(5) which directly varies with the total cost in cents. Another reason is because, it starts at the point of origin and doesn't have a y intercept.

The formula for deal 2 is a partial variation since it has a variable cost (4) and also a fixed cost(4). Another reason is because, it starts doesn't start at the point of origin and has a y-intercept of 4.

## Conclusion

**Well, which deal is better?**

To see which deal is the cheapest, look for the line that is below the other lines, on the graph and also, a point where two lines meet/intersect, for that amount of minutes, the price is the same.

As you can see, it all depends on how long you want to talk for. If you talk for 4 minutes or less, deal 1 is better, but if you love to talk, go for deal 2. If you know that you are going to be talking for only 4 minutes, go for any deal you wish as the price will be the same(shown at point(4,20)where the line intersects).### This is a limited time offer!
