On 1st January 2016 Li bought a boat for $170000

The value of the boat depreciates by 8% per year.

Work out the value of the boat on 1st January 2019

Give your answer correct to the nearest dollar.

$132,376.96

Step-by-step explanation:

The cost of the boat was $170,000, but every year, the value depreciated by 8% and he bought the boat 2016.

In 2017, the boat depreciated by 8%,

8/100 * $170000 = $13,600.

$170,000 - $13600 = $156,400.

In 2018, the boat depreciated by 8%

8/100 * $156,400 = $12,512

$156,400 - $12,512 = $143,888

In 2019, the boat depreciated by 8%

8/100 * $143,888 = $11,511.04

$143,888 - $11,511.04 = $132,376.96

The current value of the boat is $132,376.96

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
