338 (1 Year)

365.58 (3 Years)

427.68 (7 Years)

712.12 (20 Years)

Step-by-step explanation:

To find the compounded annual value, we use the formula:

Let's first take each variable and list them:

P = 325

r = 4% or 0.04

t = 1, 3, 7, 20

n = 1

Let's take each number of years one at a time.

After 1 Year

After 3 Years

After 7 Years

After 20 years

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
