Question

A boat costs $11850 and decreases in value by 10% per year how much will the boat be worth after 8 years

Answer 1

Answer: the boatf will be worth $5101 after 8 years.

A decrease of 10% is equivalent to multiplying the current value by 0.9.

Every year the value gets multiplied so we get an exponential function in years:

value after y years = $V\cdot0.9\cdot0.9\cdot\cdot\cdot0.9=V\cdot0.9^y$

value after 8 years = $\ 11850\cdot0.9^8=\ 11850\cdot0.43\approx \ 5101$

Answer 2

Answer:

Step-by-step explanation:

Keep subtracting 10 %

U will get 5101 approx.
