The equation is: 
and Julianne will begin making a profit after 168 days.
<em><u>Explanation</u></em>
Her total start-up cost is $52,000.
Each day, she spends $650 on operating costs (like utilities and wages) and she earns $960 per day from her students' lesson fees.
If the number of days to overcome the start-up cost is 
, then
the total operation cost spent in days 
and
the total students' lesson fees earned in days 
<em><u>Part A:</u></em> The equation to represent the situation will be:
<u><em>Part B:</em></u><em> </em><em> </em>Julianne will begin making a profit when....
So, Julianne will begin making a profit after 168 days.

Answer:
Water level after 24 hours will be 
.
Step-by-step explanation:
Given:
Evaporate rate of water= 0.005 inches per hour.
We need to find the level of water after 24 hours.
now we know the in 1 hour the water evaporates from a pool at a rate of 0.005 inches.
So To find the water level after 24 hrs we will multiply the evaporation rate with total number of hours which is 24 and the divide by 1 hour we get.
Framing in equation form we get;
water level after 24 hrs = 
Now to convert the number in rational form we have to multiply and divide the number by 100 we get;
Hence Water level after 24 hours will be .
