Answer:

Explanations:
The standard formula for depreciation is expressed as:

where
• r is the rate
,
• t is the time take
,
• P0 is the original price
If the car depreciates by one half every 5.5years, then P(t) = 19000
Given
Po = $38000
t = 5.5 years
P(t) = 38000/2 = $19000
Substitute

Determine the percentage rate "r"

Hence the percentage rate of decay per year is 11.84%
Determine the function showing the value of the car after t years
