Question

how many days will kitten triple its weight

Answer 1

Let "d" be the number of days gone by, then the kitten's weight at any particular day = 100 + 8d. You want to know when the weight is 300 grams so:

300 = 100 + 8d

200 = 8d

200/8 = d

d = 25

So when 25 days goes by, the kitten will have tripled its weight
