1 hour and 30 minutes to make 10 necklaces
The equation is:
and Julianne will begin making a profit after 168 days.
<em><u>Explanation</u></em>
Her total start-up cost is $52,000.
Each day, she spends $650 on operating costs (like utilities and wages) and she earns $960 per day from her students' lesson fees.
If the number of days to overcome the start-up cost is
, then
the total operation cost spent in
days
and
the total students' lesson fees earned in
days ![= \$960d](https://tex.z-dn.net/?f=%3D%20%5C%24960d)
<em><u>Part A:</u></em> The equation to represent the situation will be:
<u><em>Part B:</em></u><em> </em><em> </em>Julianne will begin making a profit when....
![960d-650d>52000\\ \\ 310d>52000\\ \\ d>\frac{52000}{310}\\ \\ d >167.741... \approx 168](https://tex.z-dn.net/?f=960d-650d%3E52000%5C%5C%20%5C%5C%20310d%3E52000%5C%5C%20%5C%5C%20d%3E%5Cfrac%7B52000%7D%7B310%7D%5C%5C%20%5C%5C%20d%20%3E167.741...%20%5Capprox%20168)
So, Julianne will begin making a profit after 168 days.
