a) To write an equation to model the problem, we need to consider the initial value of the car and the rate of depreciation. The initial value of the car in 2003 is $32,600, and it depreciates by $2,060 each year. Let $t$ represent the number of years after 2003. The value of the car after $t$ years can be represented by the equation:<br /><br />\[ V = 32600 - 2060t \]<br /><br />where $V$ is the value of the car after $t$ years.<br /><br />b) To find the number of years after which the car's value will be $18,180, we need to solve the equation for $t$ when $V = 18180$:<br /><br />\[ 18180 = 32600 - 2060t \]<br /><br />Now, let's solve for $t$:<br /><br />\[ 2060t = 32600 - 18180 \]<br />\[ 2060t = 14420 \]<br />\[ t = \frac{14420}{2060} \]<br />\[ t = 7 \]<br /><br />So, the car's value will be $18,180 after 7 years.
