MATH PUZZLE: Can you replace the question mark with a number?

Paper bag machine

In 1872, Luther Childs Crowell, a prolific inventor of Cape Cod, Mass., received a patent for a machine for manufacturing square-bottom paper bags. Patent #123,811 allowed for the bags to have two longitudinal inward folds. As a child, he spent a great deal of time folding pieces of paper, unlike most of his peers who mostly whittled and made things out of wood. In 1867, he took out his first patent for a square-bottom paper bag, and wholesale production began in 1879. It remains the standard paper bag in use throughout the world. Among his 293 patents, other inventions were a bottle-labeling machine, one for folding and wrapping magazines for mailing, and he experimented with an airplane that would be fueled by gunpowder.

Cathy was doing fine until she came to the space for 'Name of your former bank.' After a slight hesitation, she put down, 'Piggy.'
