You look at a local newspaper to post your advertisement. you find it is going to cost you $50 for the first 200 words. anything over 200 words will be an additional $0.05 per word. you've used 84 words. write this as a piecewise function.

f(x) = { cost = 50                               0 ≤ x ≤ 200

          cost = ((x-200) * 0.05) + 50        x > 200 }

Step-by-step explanation:

Given that,

First 200 words cost = $50

Anything over 200 words = $0.05 per word.

While writing a piecewise function, keep in mind that each piece of a piecewise defined function has its own domain, so we’ll also have to set-up an equation for each.

Suppose 'x' represent number of words.
