January 30, 2021## Real World Maths: Gotye and Some $$ that he got to know

November 12, 2020**Melbourne singer, songwriter, and geometrically inclined performer Gotye performing with Kimbra won 3 Grammy Awards for his song Somebody that I used to Know in 2013.**

**The Gotye youtube clip has had 1,535,344,012 or 1.5 Billion hits since it was first uploaded 5th July 2011. **

## Mini Rates Exercise:

**In 111 months Somebody that I used to know has scored 1.5 Billion hits. How many hits a. per month, b. per day, c. per minute? (Round off numbers)**

**Ans: a. 13.5 Million per month**

** b. 450,000 per day (Assuming 30 days per month)**

** c. 37,500 per hour and 625 per minute (for over 9 years non stop!)**

**Estimate of Youtube Earnings for this Song:**

**The Influencer Marketing Hub **puts the rates an advertiser pays between **$0.10** to **$0.30** per view on Youtube, but averages out at $0.18 per view. Using the lower rate, how much has this song earnt in just over 7 years?

**Earnings = 0.10 x 1.5 x 10 ^{9 } = 1.5 x 10^{8} = $150,000,000 = $150 million***

*This calculation is based on a click per view of the video. Gotye will not receive anything like $150M, however, because advertisers pay per click on their ad.

**According to the Influencer Marketing Hub again ‘on average, the YouTube channel can receive $18 per 1,000 ad views. This equates to $3 – $5 per 1000 video views.’ Again, using the lower rate:**

**Video Hits =1.5 x 10 ^{9}**

**Divide by 1,000 = 1.5 x 10 ^{9 }÷10^{3} = 1.5 x 10^{6}**

**$3.00 per 1,000 video clicks earnings = 3.00 x 1.5 x 10 ^{6} = 4.5 x 10^{6}**

**Realistic Earnings = 4.5 x 10 ^{6} = $4,500,000 = $4.5 million**

**A Geometric Parody:**

**Here is Mathspig’s take on the song:**

**Somebody that I used to Know:**

**It’ll either help students do their exercises or work like Clockwork Orange and have them running screaming out of the room when they hear the first few notes.**
