All these values will assume you are rounding to the nearest tenth
This is what the equation is going to look like
\(Y= Initial Value(1- Rate) ^{12}\)
So when we plug in the valuesÂ
\(Y=7800(1-.08)^6\)
From here you will need to follow PEMDAS
\(Y=7800(.92)^6\)
Keep following going through with the equation
\(y=7800(.60)\)
Solve
\(Y=4680\)
Because this is a word problem you have to write it in a written explanation
so
If the car constantly decreases at a rate of 8% over a time period of 6 years, at the end of the time period the car will be worth $4680
