Jarens puppy weighed 3 3/4 ounces at birth. At one week old the puppy weighed 5 1/8 ounces. At two weeks old the puppy weighed 6 1/2 ounces. If the weight of the puppy continues in this pattern, how old will the puppy be at three years old.

Respuesta :

So, the puppy gains 1.375 ounces per week.
That’s 7.875 ounces per month and 94.5 ounces per year.
Since there are 16 ounces in 1 pound, divide 94.5 ounces by 16.
That gives you 5.91 pounds per year.
Now, multiply that by 3 years.
The puppy will weigh 17.72 pounds at three years old.
