What are Cathy's profits/losses per day if she produces the profit-maximizing quantity of corn in the short run (losses are expressed as a negative number)

The question is missing a lot, so I looked for a similar question and found the attached image:

the profit-maximizing quantity is the quantity where MC = MR

in this case, the marginal revenue (or market price per unit) = $1.75

so the profit-maximizing quantity is 70 corn cobs

at this point, Cathy's total revenue = 70 x $1.75 = $122.50

Cathy's total costs = 70 x $2.25 = $157.50

Cathy's daily loss = -$35

the profit-maximizing quantity represents the quantity at which a company will either maximize profits or minimize losses, it doesn't mean that the company will always make a profit at that point.

if it is for a job, then you should learn everything you can about the job, like what does it involve, what qualification is required and how you are the right person for that job. dress appropriately for the interview. get plenty of rest the night before. good luck!
