Problema Solution
60 people are attending a conference, 60% of the memos need to be blue, 20% need to be red, 15% need to be green and 5% need to be yellow, how many green memos do I need
Answer provided by our tutors
We will assume that each person has only one memo in one color.
15% of the 60 memos need to be green means:
0.15*60 = 9 green memos
9 green memos are needed.
