Julian has 400 legos and wants to make lego models of two identical airplanes. If each airplane model requires 240 legos, how many more legos does Julian need?
Thoughts? Step-by-step reasoning:
Two aeroplanes require 240 legos / airplane x 2 airplanes = 480 legos. Julian needs 480 legos - 400 legos = 80 more legos.
Thus, the answer is 80.
