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:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
