Joe buys a new boat for $45000. It depreciates 23% a year. How much will the boat be worth after 5 years? Which of the following formulas is appropriate to use for this situation ?

a)$12180.53

b)A=P(1-r)^n

Step-by-step explanation:

The formula for depreciation to use is this case is;

A=P(1-r)^n

where

A=value of boat after 5 years

P=current value of boat = $45000

r=rate of depreciation= 23% =0.23

n=time span after the boat was boat= 5 yrs

Applying the formula

A=$45000(1-0.23)^5

A=$45000(0.77)^5

A=$12180.53

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

the correct answer is x/3+10≥32

hope this !
