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

Answer:
Step by step explanation:
Answer:
b. All real numbers
Step-by-step explanation:
Simplify:
- 5(x-2) = (15x+6)/(3) - 12
- 5x - 10 = 5x + 2 - 12
- 5x - 10 = 5x - 10
- -10 = -10
- 0 = 0
Since both sides are equal to each other, any value of x makes this equation true.
Answer:
Dont understan what you are asking
Step-by-step explanation:
OB. The digits in the millions period are 41, the digits in the thousands period are 000, and the digits in the ones period are 138.
The digits of a number can be classified into into 3 groups and each such group is called a period.
Here, we are give a number 41,000,138.
In this number, the million period consists of
ten millions - 4
and millions - 1
Hence the digits in the million periods are 41
The thousand period consists of all zeroes, hence the digits in thousand periods are 000.
The ones period contains-
hundreds - 1
tens - 3
and ones - 8
Thus, the digits in the ones period are 138
Hence, option B is the correct answer.
