To find the number of reprints (n) where mail order becomes cheaper, we set up an inequality comparing the cost of buying reprints locally to the cost of buying them through the mail. Local cost: $0.52n. Mail order cost: $0.44n + $1.20. We want to find when $0.52n > $0.44n + $1.20. Solving the inequality: $0.08n > $1.20, n > 15. Therefore, for more than 15 reprints, mail order is cheaper.
