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 grams per day,in how many days will the kitten triple its weight?

Answer 1

100 + 8d = 300; d = 25; The kitten will triple its weight in 25 days

Answer 2

So in how many days will the kitten be 300 grams?
100 + 8x = 300
8x = 200
x = 25
In 25 days the kitten will be triple its weight (300 grams).
