Step-by-step explanation:
Given:
The average cost of a computer in the year 2000 is given as:

The average cost of a computer in the year 2008 is given as:

Now, the difference in average cost between the years 2008 and 2000 can be calculated by subtracting the average cost in 2000 from the average cost in 2008.
Framing in equation form, we get:
Difference in average cost (ΔC) is given as:

Therefore, the difference in the costs for a computer between 2008 and 2000 is 
As a fraction, 69:75 would become 96/75
As a decimal 69:75 would become 0.92
As a percentage 69:75 would become 92%
Hope this helps :)
Hi there
First find the future value using the compound interest formula
The formula is
A=p (1+r/k)^kn
A future value?
P present value 1800
R interest rate 0.032
K compounded weekly 52
N time 10 years
A=1,800×(1+0.032÷52)^(52×10)
A=2,478.59
Now find the interest earned
I=A-p
A future value 2478.59
P present value 1800
So
I=2,478.59−1,800
I=678.59
It's b
Good luck!
