Answer:

Step-by-step explanation:
<u>Solving Equations</u>
We have the expression:

And it's required to make y the subject.
It can be done by isolating y on the left side of the equation and the rest of the expression on the right side.
The first step is removing the denominator by multiplying both sides by y-3:

Simplifying the right side:

Remove the parentheses:

Move the y's to the left side and the rest of the expression to the right side:

Factor out y:

Divide by x-1:

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.
It is b: False 1,729 isn’t divisible by 9
