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.

1733 is what I think is the answer.
[tex]N=c \times \frac{A}{P} \\ \\5200=c \times \frac{26000}{30} \\c= \frac{5200 \times 30}{26000}=6 \\ \\N=c \times \frac{A}{P}=6 \times \frac{52000}{30}= 10400[/tex]
