Final answer:
The number of spectators who left the contest discontented can be found by setting up an equation and solving for the total number of spectators.
Step-by-step explanation:
To find the number of spectators who left the contest discontented, we need to determine the total number of spectators and the number of spectators who left contented. We're given that 20 percent of the spectators left discontented, and 6000 spectators left contented.
Let's assume that the total number of spectators is x. We know that 20 percent of x left discontented, which can be written as 0.2x. We're also given that 6000 spectators left contented.
From the information provided, we can set up the following equation:
0.2x = 6000
To solve for x, we divide both sides of the equation by 0.2:
x = 6000 / 0.2
x = 30000
Therefore, the total number of spectators is 30000. To find the number of spectators who left discontented, we substitute x back into the equation:
0.2(30000) = 6000
6000 spectators left discontented.
