Answer:
it is about 34 days
Explanation:
divide the weight by the age for each kitten, you have a number called H
for example: kitten 1 has H1 = 600/50=12, kitten has H2 =340/28=85/7,kitten 3 has H3= 480/42= 80/7,...
find the arithmetic mean K of those number
K = (H1+H2+...+H8)/8 ≈ 13,44
so the age of the abandoned kitten is 460/13,44 ≈ 34,2 days
