Question

Ms. Boyrer is writing a program to compute ad costs. She needs to enter an algebraicrepresentation of the costs of a local paper's ad. The charge is $32.25 for up to threelines for a classified ad. Each additional line costs $6. Express the cost of an ad f(x)with x lines as a function of x algebraically.

Answer 1

Given:-

Ms. Boyrer is writing a program to compute ad costs. She needs to enter an algebraic

representation of the costs of a local paper's ad. The charge is $32.25 for up to three

lines for a classified ad. Each additional line costs $6.

To find:-

Express the cost of an ad f(x) with x lines as a function of x algebraically.

So now the algebraic equation is,

$f(x)=\begin{cases}32.25\text{ x}\leq3 \\ 32.25+6(x-3)\text{ x>3}\end{cases}$

So these is the required expression.
