Hello Guys! 
I need some help with these function problems:
1) Computer equipment can depreciate very rapidly. Suppose a business assumes that a computer will depreciate linearly at a rate of 15% of its original price each year.
..a. If a computer is purchased for $3,200, write an equation in which the value for the computer is a function of its age in years.
..b. Find the value of a computer after 3 years.
For a I was thinking:\(\displaystyle \L \;v(t)\,=\,3,200\,-\,480t\)
And for b:\(\displaystyle \L \;v(3)\,=\,3,200\,-\,480(3)\,\,\;\;\Rightarrow\,\,\,\;v(t)\,=\,1,760\)
2) A clothing store is selling all out-of-season clothing at 30% of the original price.
..Write a function that gives the discounted price as a function of the original price.
My book says:\(\displaystyle \L \;S(P)\,=\,.7p\,\) How in the world did that happen?
