Final answer:
Bimala brought home 6 cartons of eggs, calculated by dividing the total number of broken eggs (30) by the number of broken eggs per carton (5).
Step-by-step explanation:
Bimala bought 150 eggs in five crates, and after discovering 30 eggs were broken with 5 eggs broken in each carton, we need to calculate how many cartons she brought home. To find the number of cartons, we divide the total number of broken eggs by the number of broken eggs per carton. This gives us 30 broken eggs ÷ 5 broken eggs/carton = 6 cartons. Therefore, Bimala brought home 6 cartons of eggs.
