A stained glass artist has a fixed cost of $150. It costs the artist $15 to produce each piece, but each piece sells for $35. The equation C=150+15n represents the total cost, C, for producing n pieces. The total revenue for n pieces is determined by the equation R= 35n. What constraints are necessary to include when modeling this situation?
