The equation is:  960d-650d=52000 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  d , then

the total operation cost spent in  d days = \$650d and

the total students' lesson fees earned in  d days = \$960d

<em><u>Part A:</u></em>   The equation to represent the situation will be:   960d-650d=52000  

<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

So, Julianne will begin making a profit after 168 days.

A)clara believes the sequence 3,9,27,81,243 is arithmetic. Do you agree with clara?Explain your reasoning.
allsm [11]
This is NOT an arithmetic sequence because there is no common difference.  It is a geometric sequence because there is a common ratio.  Meaning that each term is a constant ratio or multiple of the previous term.  The recursive rule for this geometric sequence is:

a(n)=3*a(n-1), a(1)=3
