After checking the information of the table, it is to notice that the table fulfills the behavior of a <em>direct</em> relationship described by the <em>linear</em> equation y = 0.9 · x. #SPJ1

<h3>How to analyze a relationship between the two variables</h3>

Let be <em>x</em> and <em>y</em> the <em>original</em> investment and the value after applying the change, both in monetary units. A <em>direct</em> relationship is observed by following this model:

y = (1 + r/100) · x     (1)

Where <em>r</em> is change rate, in percentual units.

After checking the information of the table, it is to notice that the table fulfills the behavior of a <em>direct</em> relationship described by the <em>linear</em> equation y = 0.9 · x. #SPJ1

<h3>Remark</h3>

The table of the <em>change</em> in investment with respect to <em>initial</em> investment is missing and is now introduced below:

<em>(x₁, y₁) =</em> (75, 7.5), <em>(x₂, y₂) =</em> (100, 10), <em>(x₃, y₃) =</em> (200, 20), <em>(x₄, y₄) =</em> (300, 30), <em>(x₅, y₅) =</em> (400, 40)

Dan was getting rs. 100 for 5 years at an interest rate of 5%. Find the accumulated value of annuity at the end of 5 years
Citrus2011 [14]

The future value of the annuity after the end of 5 years is $552.56.

Given that, r =5%= 0.05, 5 years  = 5 yearly payments, so n = 5, and P = $100.

<h3>What is the annuity formula?</h3>

The formula to find the annuity formula FV=\frac{P \times ((1+r)^{n}-1 )}{r}.

Now, FV=\frac{100 \times ((1+0.05)^{5}-1 )}{0.05}

⇒FV = 100 × 55.256

⇒FV = $552.56

Therefore, the future value of the annuity after the end of 5 years is $552.56.
