Every year, Danielle Santos sells 120,366 cases of her Delicious Cookie Mix. It costs her $1 per year in electricity to store a case, plus she must pay annual warehouse fees of $4 per case for the maximum number of cases she will store. If it costs her $743 to set up a production run, plus $10 per case to manufacture a single case, how many production runs should she have each year to minimize her total costs?
