Answer 1

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

$p = 95\%$ --- Yet to arrive

$Seated = 155$

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:

$5\% * x = 155$

Where x represents the total number of tickets

Make x the subject

$x = \frac{155}{5\%}$

$x = \frac{155}{0.05}$

$x = 3100$
