Julianne opens a dance studio. her start-up costs for the building, advertising, and supplies total $52,000. each day, she spends $680 on operating costs (like utilities and wages). she earns $960 per day from her students' lesson fees. part a: write an equation or inequality to represent this situation. let d be the number of days. part b: when will lulianne begin making a profit? show all the work you did to arrive at your answer

Alright, lets gets started.

Jullianne's start-up costs for the building, advertising, and supplies total $52,000.

she spends $680 on operating costs on daily basis.

Means Suppose the days d, the operating cost will be=

This cost will be added in her start up cost.

The earning for d days will be =

So, part A :

Now suppose after d days, she will start making profit means, after d days, her cost will be equal to her earning.

So, part B:

Subtracting 680 d from both sides

Dividing 280 in both sides

Means after 19 days, she will start making profit.   :    Answer

Hope it will help :)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

wth is with the little mtn top and what are you talking about like fix your words and accually make sence with them and i like was in a completly different question like three times like it seems like your ilitteret
