Darlo is your average foreign exchange student.
- 00:11
He hails from a country no one can pronounce, dresses like it’s 1978, and is hopelessly [Darlo holding his lunch tray]

in love with the wrong girl.

Unfortunately, his only talent is…disco dancing. [Darlo starts disco dancing]
- 00:28
Darlo boogies away to the tune “Disco Love” three times…
- 00:33
…then dances for six minutes of “Dance Fever.” [Darlo dancing under spotlights]
- 00:36
If Darlo dances for a total of ten minutes before getting annihilated by McKenzie’s
- 00:41
big boyfriend…
- 00:42
…can you determine how long the song “Disco Love” is?
- 00:46
First we’ll need to find the variable. [McKenzie finds the variable hiding behind the sofa]
- 00:48
Since we want to solve for Disco Love’s length, we’ll make that our “x”.
- 00:52
Darlo dances “Disco Love” three times, so we’ll call the total time it took him
- 00:57
to dance that song… 3x.
- 00:59
Now we’ll add the six minutes he grooves to “Dance Fever.”
- 01:02
Darlo dances for a total of 10 minutes.
- 01:05
So… 3x + 6 = 10
- 01:07
To get all the x’s on one side, we can subtract 6 from both sides to get 3x equals 4.
- 01:16
Remember to make the same move on both sides of that equal sign to maintain equality. [Darlo appears doing a dance move on both sides of the equation]
- 01:21
To solve for x, we then divide both sides by 3.
- 01:24
3x divided by 3 equals x... so there you have it!
- 01:28
x equals four-thirds.
- 01:29
Or, expressed as a mixed number… [Darlo holds his hands up and looks unsure]
- 01:33
1 and 1/3 minutes.
- 01:34
To find 1/3 of a minute, we multiply 1/3 by 60, the number of seconds in a minute…
- 01:40
…or divide 60 by 3, to get 20. [Clock spinning round]
- 01:43
Which means that “Disco Love” is one minute and twenty seconds, uh… too long.
- 01:47
Darlo, next time you fall for a girl, make sure her boyfriend isn’t on the football [Darlo is chased by various sports teams]
- 01:50
team.
- 01:51
Or the basketball team.
- 01:52
Or the soccer team…
