Annual Interest Rate = 6%
Total amount John should
receive after a year = 2000x(1+0.06)
= 2120
Total interest amount in a year = 2120 - 2000
= $120
Total interest amount in a per month = 120/12 = $10

Step-by-step explanation:
Given
In 1990; Income= $39000
In 2010; Income= $70768
Solving (a): An equation in form of f(x) = ax + b
First, we need to determine the slope, a
Taking y as income and x as year index.
When x = 0; y = 39000
When x = 20; y = 70768
Substitute these values in the above formula
Next, is to determine the formula using:
<em>Considering :When x = 0; y = 39000, we have</em>
<em /><em />
<em /><em />
<em>Make y the subject of formula</em>
<em /><em />
<em />
<em>Express y as a function of x</em>
<em /><em />
Solving (b): Income in 2005
<em>In 2005, x = 15</em>
So:
becomes
