Answer:
The car will be worth £2516.22 in 5 years
Step-by-step explanation:
The rule of depreciating is
, where
- <em>A</em> is the new value
- <em>P</em> is the original value
- <em>r</em> is the rate in decimal
- <em>t</em> is the time in years
∵ Dan buys a car for £2700
∴ <em>P</em> = 2700
∵ It depreciates at a rate of 1.4% per year
∴ <em>r</em> = 1.4% = 1.4/100 = 0.014
∵ We need to find how much it will be worth in 5 years
∴ <em>t</em> = 5
→ Substitute all of these values in the rule above to find A
∵
→ Use your calculator to find the answer
∴ <em>A</em> = 2516.22
∴ The car will be worth £2516.22 in 5 years
