Quant Lit Task 4

The information we be seeking in this exercise is to algebraically solve and graphically show the two savings computer programs so we can find a break even point, the residuum of the accounts at 14 months and the balance of the accounts at 23 months.
savings stick out A is represented by adding $ cd to the reaping of $20 multiplied by the number of periodic accommodates.
$four hundred+20X=Y
The balance of savings plan B is found by adding $600 to the product of $10 multiplied by the number of monthly deposits.
$600+10X=Y
In order to find a constant inconstant we are going subtract one plan from the other.
20x+400=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 will 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
resolving is the ordered equal (20,800)
This is because in both equations when X=20 Y=800.
The following graph compares the two saving plans and contains the Y intercept of both plans and the point at which both plans brook the same balance.

If we use the graph to find the balance of Plan A after 14 months we see the ordered pair (14,$680) with plan B we see the ordered pair (14,$740).



By comparing these two points we know that after 14 months savings plan B will have a larger balance.

If we use the graph to find the savings plan of from each one 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 will have the larger balance of the two.

The cause Quadrant one is the relevant quadrant is because we are start with positive 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 functional 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: Orderessay
