Dauzat - 8 SP.A.3 Vet

Question

A veterinarian collected data about the growth of a puppy during the first 9 weeks after birth. The veterinarian wrote the equation n=1.6w + 3 to show the relationship between the age of the puppy, w, in weeks and its weight, n, in ounces.

Describe the relationship between the age of the puppy and the weight in ounces.

Drag the correct number below into the appropriate box to describe the relationship.

The weight of the puppy was initially
ounces. The weight increased by
ounces every
week(s).

Answer 1

To describe the relationship as provided by the equation \( n = 1.6w + 3 \):

• The initial weight of the puppy (when \( w = 0 \)) is found by substituting \( w = 0 \) into the equation: \[ n = 1.6(0) + 3 = 3 \text{ ounces} \]
• The coefficient of \( w \) is 1.6, which indicates that the weight of the puppy increases by 1.6 ounces for every week.

Putting this information into the boxes:

• The weight of the puppy was initially 3 ounces.
• The weight increased by 1.6 ounces every week.
