Question

4. The pet store usually sells 12 puppies every 9 days. At this rate, how long will it take

them to sell 174 puppies?

Answer 1

Approximately 131 days

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,

`(12)/(9) = (174)/(x) \\ \\ x = (174 * 9)/(12) \\ \\ x = (1,566)/(12) \\ \\ x = 130.5 \: \\ \\ x \approx \: 131 \: days`
