Using the given function, it is found that:
The profit when n students are enrolled in the class is given by:
f(n) = 70n - 400.
A profit is made when f(n) > 0, hence:
70n - 400 > 0
70n > 400
n > 5.71.
6 students need to be enrolled for the instructor to make a profit.
A profit of $1,000 is made when f(n) = 1000, hence:
70n - 400 = 1000
70n = 1400.
n = 20.
20 students must be enrolled for the instructor to make a profit of $1,000 a month.
