The numbers on the houses on the north side of Elm Street are consecutive odd numbers starting with l (1. 3, 5, etc.). The plastic digits used to number the houses cost 4 ¢ each. (It costs 4¢ to label house number 9 and 8¢ to label house number 11.) If it costs $5.00 to number all the houses on the north side of Elm Street, what is the house number of the last house?
