The stock of Company A lost $4.17 throughout the day and ended at a value of
Anit [1.1K]

Answer:

4%

Step-by-step explanation:

After losing 4.17, it came down to 100.08, so the opening price was:

100.08 + 4.17 = 104.25

To find percentage decline, we find the ratio of the "change" (which is 4.17) divided by the opening (original) price, which is 104.25. Then we multiply that fraction by 100 to get our percentage decline.

So,

\frac{4.17}{104.25}*100=4

Thus, the

percentage decline = 4%

Designer Dolls, Inc. found that the number N of dolls sold varies directly with their advertising budget A and inversely with th
Travka [436]

Answer:

D


Step-by-step explanation:

Direct Variation takes the form  A = kB  

Inverse Variation takes the form  A=k(\frac{1}{B})

  • Where A and B are the 2 variables associated and k is the proportionality constant.

<em>Since </em><em>number of dolls [N] </em><em>varies </em><em>directly </em><em>with </em><em>advertising budget [A],</em><em> in our equation, </em><em>A should go in the numerator</em><em> and since </em><em>number of dolls [N] </em><em>varies </em><em>inversely</em><em> with </em><em>price of dolls [P]</em><em>, </em><em>P should go in the denominator.</em>

Thus we can write our equation as:

N=k(\frac{A}{P})

Solving this equation for k given the information "The company sold 5200 dolls when $26,000 was spent on advertising and the price of a doll was set at $30":

N=k(\frac{A}{P})\\5200=k(\frac{26,000}{30})\\5200=k(866.67)\\k=\frac{5200}{866.67}=5.99

Rounding k=5.99 to k=6


Now, given that we want to find the number of dolls [N] when A=52,000  and  P=30 , we have:

N=(6)(\frac{52,000}{30})\\N=10,400 dolls

Answer choice D is correct.
