Suppose a firm has the ability to produce soap, toothpaste, or both. if the firm produces q subscript upper s units of soap and no toothpaste, then the total cost of production will be $33 thousand. if instead the firm produces q subscript upper t units of toothpaste and no soap, then the total cost of production will be $15 thousand. however, if the firm produces both q subscript upper s units of soap and q subscript upper t units of toothpaste, then the firm's total cost of production will be $46 thousand. does this firm potentially experience economies of scope, diseconomies of scope, or no economies of scope?

Caleb construction (cc) incurs supervisor salaries expense in the construction of homes. if cc manufactures 100 homes in a year, fixed supervisor salaries will be $400,000. with the current construction supervisors, cc's productive capacity is 150 homes in a year. however, if cc is contracts to build more than 150 homes per year, it will need to hire additional supervisors, which are hired as full-time rather than temporary employees. cc's productive capacity would then become 200 homes per year, and salaries expense would increase to $470,000. how would cc’s salaries expense be properly classified? fixed variable mixed stepped curvilinear
