Mona Persian wants to consider expanding her small business. She makes decorative ceramic pet food bowls that are sold in an upscale local pet supply shop, "Jessica's Designer Pet Apparel Boutique". Mona can produce up to 100 per month. She has a fixed cost of $550.31 per month for her home office. She has estimated that the cost of the materials and labor for the bowls is $2.00 per unit. The boutique purchases the bowls for $12.00 per unit.

Determine the monthly profit or loss if Mona makes 50 bowls per month. Assume that she can sell all that she makes.
