Answer:

The percent decrease is [tex]37.5\%[/tex]

Step-by-step explanation:

we know that

[tex]8\ tickets[/tex] ------> represent the [tex]100\%[/tex]

so

by proportion

Find the percent decrease

[tex]\frac{100}{8}\frac{\%}{tickets} =\frac{x}{(8-5)}\frac{\%}{tickets} \\ \\x=100*(8-5)/8\\ \\x=100*3/8\\ \\x=37.5\%[/tex]
