Real-Life Math -- Solution
First, you must forget the standard decimal system that is based on 5s and 10s. Think 30, as in 30 seconds or one-half a minute. And think 60, as in 60 seconds or one full minute.
"There is no calculator in the world that will compute on a base of 60," says David Hirt, a voice-over performer in Georgia.
"Make sure that you don't think of a minute being a hundred seconds -- you'll short yourself some money."
Here is what you've done:
2 at 20 seconds
2 at 30 seconds
2 at 45 seconds
1 at 60 seconds
1 at 90 seconds
First, total the seconds.
2 X 20 seconds = 40 seconds
2 X 30 seconds = 60 seconds
2 X 45 seconds = 90 seconds
Now, add the time:
40 + 60 + 90 + 60 + 90 = 340
Your total is 340 seconds.
Then, calculate your billable units.
Divide 340 by 30, since your pay is based on a 30-second scale.
You get 11.3 units of work.
Now, multiply 11.3 times the $200 per unit of work and you get $2,260 for your performance in the studio.
