Explanation:
A dog owner observes that from birth to age 14 weeks, the puppy’s weight can be modelled by the equation

In this equation,
- number 365 represents the initial weight of puppy;
- number 1.23 can be rewritten as 1+0.23, where 0.23 (or 23%) is the rate of weight increase.
When w=4,000, then

This means that puppy will weight 4,000 grams nearly at the middle between 11th week and 12th week.
