Answer :
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,
[tex]f(x)=\begin{cases}32.25\text{ x}\leq3 \\ 32.25+6(x-3)\text{ x>3}\end{cases}[/tex]So these is the required expression.
