Total Revenue is equal to 850 weeks.
Total Cost is equal to the sum of Total Fixed Cost and Total Variable Cost. The Total Fixed Cost is equal to 7500 and the Total Variable Cost is equal to 300 weeks.
For him to earn he should have a positive profit.
Profit = Total Revenue - Total Cost >= 0Profit = 850 weeks - (7500 + 300 weeks) >= 0850 weeks - 7500 - 300 weeks >= 0550 weeks - 7500 >= 0 (Model)
The minimum number of weeks can be solved by considering the break-event point (i.e. zero profit).550 weeks - 7500 = 0
weeks = 14.
