The dean of the Western College of Business must plan the school’s course offerings for the fall semester. Student demands make
it necessary to offer at least 30 undergraduate and 20 graduate courses in the term. Faculty contracts also dictate that at least 60 courses be offered in total. Each undergraduate course taught costs the college an average of $2,500 in faculty wages, and each graduate course costs $3,000. How many undergraduate and graduate courses should be taught in the fall so that total faculty salaries are kept to a minimum?

Explanation:
please find attached the table referred to in this question and a second table where marginal cost is included
A perfect competition is characterised by many buyers and sellers of homogeneous goods and services. Market prices are set by the forces of demand and supply.
in a perfect competition, price = marginal cost = marginal revenue
Marginal cost = total cost 2 - total cost 1
e.g. marginal cost at 2 units of output = $7 - $2 = $5
Hank and Helen would supply at the point where marginal cost is equal to $5.
looking at the second attached table, there are two points where marginal cost is equal to $5. at output 1 and output 5.
at output one, Hank and Helen would be earning a loss because total cost is greater than total revenue. so they would not supply at this point.
at output five, Hank and Helen would earn a profit and thus would supply at 5 units of output.
Since all firms face and identical cost structure, the industry supply would be 100 x 5 = 500 pounds
