Answer-

The equation is and Julianne will begin making a profit after 168 days.

Solution-

Julianne's start-up cost = $52,000,

Each day, she spends = $650,

and she earns = $960 per day,

If 'd' is the number of days to overcome the start-up and daily operation cost, then  

total operation cost of d days = $650d and  

total student lesson fees earned in d days = $960d

∴ The equation to represent the situation is,

∴ Julianne will begin making a profit,

where is the figure
