Question:

An hour before show time, only 155 people are seated for rockfest. According to the ticket sales, 95% of the people have yet to arrive. How  many tickets were sold?

Answer:

3100 tickets

Step-by-step explanation:

Given

[tex]p = 95\%[/tex] --- Yet to arrive

[tex]Seated = 155[/tex]

Required

Determine the total number of people

If 95% are yet to arrive, then 5% have arrived (i.e. 100% - 95%)

So, the total number of people is calculated as:

[tex]5\% * x = 155[/tex]

Where x represents the total number of tickets

Make x the subject

[tex]x = \frac{155}{5\%}[/tex]

[tex]x = \frac{155}{0.05}[/tex]

[tex]x = 3100[/tex]
