To encourage large orders from distributors, the manufacturer will reduce the price by \$0.01 per unit for each unit in excess of 100 units. (For example, an order of 101 units would have a price of \$79.99 per unit, and an order of 102 units would have a price of \$79.98 per unit.) This price reduction is discontinued when the price per unit drops to \$61. Express the price per unit as a function of the order size.
