Given: julianne total startup cost = $52000
Operating cost per day =$680
Earn money from her lesson fee per day = $960

Given d be the number of days
To proof: julianne spends on operating cost in d day = $680d
julianne earn from lesson fee in d day = $960d
Total profit in d day = 960d-680d
Part A) Total profit should be greater than 52000. Because this is startup investment.
According to question inequality becomes
Part B) Now solve for d
After 186 days, Julianne will get profit from dance studio.
