Answer:

$1400

Step-by-step explanation:

We are given the following from the question;

Cost price of the car = $45,000

If the value depreciates by one-half after 3.5years,;

Depreciation = 45000/2 = 22500

Value after 3.5 years = 45000 - 22500 = $22500

After another 3.5 years, it will reduce by one half again, the price will become;

After 7 years;

Price = 22500 - (0.5 * 22500)

Price = 225000 - 11250

Price = $11250 after 7 years

After 10.5 years(additional 3.5 years), the price will become;

Price = 11250 - (0.5*11250)

Price = 11250 - (5625)

Price after 10.5years = $5625

After 14years;

Price of the car will become = 5625 * 0.5 = $2,812.5

After 17.5years (additional 3.5years)

Price will reduce by one half again.

Price after 17.5years = $2,812.5*0.5

Price after 17.5years = $1,406.25

Hence the value of the car 17 years after it was purchased, to the nearest hundred dollars is $1400
