Designer Dolls, Inc. found that the number N of dolls sold varies directly with their advertising budget A and inversely with the price P of each doll. The company sold 5200 dolls when $26,000 was spent on advertising and the price of a doll was set at $30. Determine the number of dolls sold when the amount spent on advertising is increased to $52,000. Round to the nearest whole number.

Answer:
The number of dolls sold 10,400
Step-by-step explanation:
Given: The number N of dolls sold varies directly with their advertising budget A and inversely with the price P of each doll.
N = k(A/P), where k is the constant.
Now we have to find k.
Given: N = 5200, A = 26,000 and P = 30
5200 = k (26000/30)
5200 = k(866.67)
k = 5.99, when we round off we get k = 6
Now let's find the number of dolls sold when the ad amount increase to $52,000
Now plug k = 6, A = 52000 and p = 30
N = 6(52000/30)
N = (52000/5)
N = 10.400
Therefore, the number of dolls sold 10,400

To solve this problem, we can set up proportion, which is two equivalent ratios. In this case, we are using the ratio of A to B to figure out the amount that B pays using our value for A. We are allowing x to represent the unknown value for the B payment. This is modeled below:
3/2 = £125/x
To simplify, we can perform cross-multiplication. This means multiplying the numerator of one fraction by the denominator of the other and setting it equal to the product of the other numerator and denominator. This is modeled below:
(125)(2) = (3)(x)
Next, we can simplify the equation by performing the multiplication on both sides of the equation.
250 = 3x
Finally, we should divide both sides by 3 to get our unknown variable x alone on the right side of the equation.
x = 83.33
Therefore, B costs £83.33.
