Answer:
90% chance that it could happen.
To answer this question, we have the start-up costs of $ 52,000
A monthly inflation of $ 0 is assumed
Operating costs are $680
The daily gain is $960
For the Part A.
The inequality that this situation represents

So:

Where d represents the number of days.
For the Part B.
To start earning, you must replace all the initial investment and cover the expenses per day. The time that must pass for this to happen is obtained by clearing "d" from the inequality.

d> 185.71 days
Then, the sum of the net profits will be greater than the initial investment after 186 days of starting the business.
Step-by-step explanation:
Since there is 2 unknown variable ,
so we need 2 equation to find their values.
First we are gonna find the 3% of $3000 and take it from the $157.50.
3000 x 0.03 = $90
157.60 - 90 = $67.50
Then we are gonna find the amount that 4.5% of is equal to $67.50.
4.5/100=67.50/x (cross multiply)
4.5x = 67.50x100
4.5x = 6750 (divide both sides by 4.5)
4.5x/4.5 = 6750/4.5
x = 1500
Therefore the amount she earned in sales is $3000 + $1500 = $4500
Please consider the complete question.
A parking lot in the shape of a trapezoid has an area of 12,052.1 square meters. The length of one base is 82.4 meters and the length of the base is 108.6 meters. What is the width of the parking lot
We will use area of trapezoid to formula to solve our given problem.
, where
a and b represents parallel sides of trapezoid,
h = height of trapezoid.
Width of the trapezoid will be equal to height.
Upon substituting our given values in above formula, we will get:





Therefore, the width of the parking lot is 126.2 meters.
