Question

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 1

1733 is what I think is the answer.

Answer 2

`N=c * (A)/(P) \\ \\5200=c * (26000)/(30) \\c= (5200 * 30)/(26000)=6 \\ \\N=c * (A)/(P)=6 * (52000)/(30)= 10400`
