Problema Solution
Bamboo the elephant weighed 235 lb at birth. Each month Bamboo has gained 180 lb. if bamboo now weighs 1495 lb, how old is she ?
Answer provided by our tutors
let
b = 235 the weight at birth
n = 1495 lbs the weigh of Bamboo now
x = the number of months passed
each month Bamboo gained 180 lb thus we can write the following function for the weight depending on x the months passed
f(x) = 235 + x*180
we need to find for what value of x, f(x) = 1495 that is
235 + x*180 = 1495
x = (1495 - 235)/180
x = 7 months
Bamboo is 7 months old.
