In 2003,the price of a certain automobile was approximately $31,900 with a depreciation of $1,580 per year. After how many years will the car’s value be $24,000

a) Write the equation to model the problem. Let t represent the number of years after 2003. For example the year 2005 would be represented by t=2
Answer:

b) solve the equation to find the answer to the equation above (note:Include the units,in this case years)
Answer:

Answer 1

Check the picture below.

so when p = 24000, what's "t"?

`p=31900-1580t\implies \stackrel{ p }{24000}=31900-1580t\implies 0=7900-1580t \\\\\\ 1580t=7900\implies t=\cfrac{7900}{1580}\implies t=5`
