Select the function that represents the simple interest formula. A. A) = P(1 + )-

B. A(n) = P + (n-1)i*P

Step-by-step explanation:

The formula to determine the simple interest formula is given below:

Simple interest = P×r × t

where

P denotes the principal

r denotes the rate of interest

And, t denotes the number of years

Now we replace i with the t

So,

SI = Pni

Now for n-1 years, the simple interest is

SI = P(n - 1)×i

So, the total amount would be

A(n) = P + (n - 1)i × P

From the graph, we can see that the set of ordered pairs which belongs to the line are

D). (2, 100), (3, 150), (5, 250)

Because x-axis is the first coordinate and y-axis is the second coordinate. In options B and C, they are

arranged in the wrong place. In option A, point (3,125) doesn´t belong to the line.
