The cost of screen for window = 864.

We have,
- A rectangular window of length = 3ft and breadth 2 ft.
Fir solving,
- As the answers should be in sqaure inches let us first convert ft in inches.
- Then, we will find the area of window and as the cost of screen is same as that of area,we will find it.

We kow that,
Taking this in mind, convert the values
= Length = 3 ft
= Length = 3 × 12
= Length = 36 inchees
= Breadth = 2ft
= Breadth = 2 × 12
= Breadth = 24 inches
<u>★</u><u>Area</u><u> </u><u>of</u><u> </u><u>window</u><u>:</u>
We know that,
= Area of rectangle = Length × Breadth
= Area = 36 × 24
= Area = 864 inches²
As, area of window in square inches equal to cost of the screen.

Step-by-step explanation:
Just use some algebra to collect the like terms from each side
Answer:
(a) 20256.15625
(b) 17642.78546
Step-by-step explanation:
(a) There's a formula for this problem y = A(d)^t where, A is the initial value you are given, d is the growth or decay rate and t is the time period. So, in this case, as the car cost is decreasing it is a decay problem and we can write the formula as such; y = A(1-R)^t
So, in 5 years the car will be worth, 25500(1-4.5%)^5 or 20256.15625 dollars
(b) And after 8 years the car will be worth 25500(1-4.5%)^8 or 17642.78546 dollars.
