The simple interest formula is a = p(1 + r)t where p represents the amount originally deposited, r is the interest rate, and a is the amount in the account after t years.
find r if a = 2700, p = 2200 and t = 5.
2700 = 2200(1 + r)5
express r as a percentage to one decimal place (x. x%).

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
