90 points one question 2 answers show work !

Part A)

Total costs $52,000

Each day spends $680 and earns $960

Let d be the number of days

So the total number of spending days plus total cost has to be less than the total number of earnings for her make profit.

680d + 52,000 <= 960d

Part B)

Solve the equation above

680d + 52,000 <= 960d

52,000 <= 960d - 680d

52,000 < = 280d

52,000 / 280 <= d

185.7 < d

or

d > 185.7

So Julianne will begin making profit at 188 days.
