Aboat costs 19,200 and decreases in value by 12% per year. how much will the boat be worth after 5 years

Answer

Find out the how much will the boat be worth after 5 years.

To prove

As given

A boat costs $19,200 and decreases in value by 12% per year.

This is denoted by the exponential decreasing function.

y = a (1 - i)^{t}

Where y is the intial value, i is the interest in the decimal form and t is the time.

Here

a =  $19,200

t = 5 years

i = 12 %

12% is written in the decimal form

= 0.12

Put in the formula

y = 19200(1 - 0.12)^{5}

y = 19200 × 0.527732

y = $10132.5 (Approx)

Therefore  the boat  worth after 5 years will be $10132.5 (Approx)

the answer for this is 0.25 km. : )
