The area to be fenced in is 20 ft by 45 ft, or 900 ft^2. But "25 per foot based on the area" is illogical. Please ensure that you have copied this problem down accurately, and be sure to provide units of measurement: did you mean $25 per square foot, or per foot, or what?
The fencing cost is usually dependent on the unit cost and the length of the yard perimeter. The perimeter is P = 2L + 2W, which here is P = 2(45 ft) + 2(20 ft), or 130 ft. If the fencing is 25 cents per foot, $130 ft of fencing would come to $32.50.
Answer:
The function to determine the value of your car (in dollars) in terms of the number of years t since 2012 is:

Step-by-step explanation:
Value of the car:
Constant rate of change, so the value of the car in t years after 2012 is given by:

In which f(0) is the initial value and r is the decay rate, as a decimal.
In 2012 your car was worth $10,000.
This means that
, thus:

2014 your car was worth $8,850.
2014 - 2012 = 2, so:

We use this to find 1 - r.






Thus
