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

Answer 1

So first you need to make an equation, let x represent the number of days:

100+8x=300
-100 -100

8x=200

Divide both sides by 8

8x/8=200/8

x=25
So your answer is 25 days

Answer 2

let number of days = x, then

100 + 8x = 300
8x = 300-100 = 200
x = 200/8 = 25 days answer
