You buy a used truck for $20,000. The truck depreciates 7% per year. What is the value
of the truck after 8 years?

$11,191.64

Step-by-step explanation:

Depreciation is the decrease in worth an item experiences as it is being used to perform it's needed function and the formula for Depreciation of these Valuables is generally given as:

D = P × [1 - r/100]^n

Where D = the new depreciated value after n period.

P= initial value of item

r= rate of depreciation

n= duration of depreciation being considered.

As given in the question, P= $20,000. r =7%, n = 8years, then the depreciated value after 8years becomes:

D= 20,000 × [1 - 7/100]^8

D=$11,191.64

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
