What is the cost of a match factory?
I bought a box of matches today in the Rep of SA. The cost was 50 cents. The box contained thirty matches, making the cost per match 50/30 = 1,6666 cents/match.Lets us assume that 1/3rd of the world's population of 6 billion (a million million), that's 2 million million people, strike one match per day 365 days of a year.We therefore have 2,000,000,000,000 x 365 matches being struck every year.So, 2,000,000,000,000 x 365 x 1,6666 divided by 100 will give you the golbal sum spent annually by 1/3 of the the world's population striking one match every day for a year in South African Rands.12,166,180,000,000 Rands12,166 Billion Rands
