Tom [10]

Answer:

option A  is answer.

Step-by-step explanation:

Amount of interest earned for compounded monthly  for $1 = 1.040742

Amount of interest earned for compounded quarterly for $1= 1.040604

Difference for $1  =   1.040742 - 1.40604

Difference for $7000 = $7000x0.000138

                                      or $0.96

Designer Dolls found that its number of Dress-Up Dolls sold, N, varies directly with their advertising budget, A, and inversely
Radda [10]

Answer:

25,600

Step-by-step explanation:

You can use the rule of three considering that the number of dolls sold varies directly with the advertising budget:

$54,000    →   9,600

$144,000   →       x

x=\frac{144,000*9,600}{54,000}

x=25,600

According to this, the number of dolls sold if the amount of advertising budget is increased to $144,000 is 25,600.
