Answer:
Approximately 131 days
Step-by-step explanation:
Let the store will take x days to sell 174 puppies.
Since, there is a relation of direct proportion between the puppies sold and number of days.
So,
[tex] \frac{12}{9} = \frac{174}{x} \\ \\ x = \frac{174 \times 9}{12} \\ \\ x = \frac{1,566}{12} \\ \\ x = 130.5 \: \\ \\ x \approx \: 131 \: days[/tex]
