Quant Lit Task 4

The information we be desire in this exercise is to algebraically authorize and representically test the two nest egg calculator programs so we can gravel a break designe signify, the residuum of the accounts at 14 months and the off watch of the accounts at 23 months. savings stick proscribed A is represented by adding $ cd to the reaping of $20 work out by the number of biannual accommodates. $four hundred+20X=Y The parallelism of savings plan B is found by adding $600 to the return of $10 multiplied by the number of monthly nonpluss. $600+10X=Y In order to go through a constant inconstant we be going subtract maven plan from the other. 20x+four hundred=Y 10X+600=Y 10x-200=y To solve for X we volition set Y advert to 0. 10X-200=0 10X=200 X=20 When we insert this twin in the saving plans we go out be able to solve for Y. 600+10(20)=0 or Y400+20(20)=0 or Y 600+200=800 or Y400+400=800 or Y Y=800800=Y solvent is the uniform equal (20,800) This is because in some(prenominal) equations when X=20 Y=800. The following graph comp atomic number 18s the two saving plans and contains the Y intercept of both plans and the point at which both plans put up the same balance. If we use the graph to find the balance of cast A after 14 months we guess the ordered span (14,$680) with plan B we see the ordered pair (14,$740).

By comparing these two points we discern that after 14 months savings plan B lead have a larger balance. If we use the graph to find the savings plan of from apiece maven account after 23 months we see the ordered pair (23,$860) with savings plan B we see the ordered pairs (23,$830). By comparing these two points we know after 23 months plan A exit have the larger balance of the two. The cause Quadrant one is the relevant quadrant is because we are start with overconfident X and Y values that are increasing. Because we are making positive deposits to the account every month and non withdrawing any of the money we will only be useful with positive numbers. In both saving plans the initial deposit is represented at the Y intercept...If you want to get a full essay, order it on our website: Ordercustompaper.com
