3.1 Attempted on a separate piece of paper.

3.2 In class today we learned how to solve inequalities and graph them on number lines. We also learned how to graph them on coordinate planes. When you have a inequality like x>5 on a number line and on a coordinate plane the similarities are that both show how many possibilities you can have to prove the inequality is true. The same thing happens for X<-3 just that the line will face an opposite direction because it is a negative number. In a inequality like y<2x+1 this would have to be done on a coordinate plane. The side of the line with the most y-coordinates is the side to shade. you can also determine by the less than or greater than sign.

3.4 Attempted on a separate piece of paper.

3.5 A. You need to change the dependent variable in which this case is the .30 cent

B. I would change the mileage fee because the flat rate is the foundation your company will barely make any money if the person traveled a mile in the truck and no flat rate. I would charge $40 for a flat rate and .20 cents for a mileage fee. It shows competition with other companies.
