Question

An online bargain print service charges $p for the first 200 business cards and $x for each set of 100 above the first 200. Express the cost of the cards algebraically as a piecewise function

Answer 1

F(n) = pn ;p + nx

Explanation:

Expressing cost of cards as a piecewose function :

Number of cards, x up to 200

For n ≤ 200 ; charge = $p * n

For each set of 100 after 200;

a > 200

Each set of 100 = $x

n = (a - 200) / 100

Cost = $p + $x * n
