Question

Kittens weigh about 100 grams when born and gain 7 to 15 grams per day. If a kitten weighed 100 grams at birth and gained 8 pounds per day, in how many days will the kitten triple it's weight? How do I write this as an equation, and how do I find the answer?

Answer 1

You can set up an equation such as 300=100+8x where x is equal to the number of days gone by since birth. The answer would be 25 days.

Answer 2

The equation would be 300=100+8d. All you would have to do is solve for d.
