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

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 = (155)/(5\%)`

`x = (155)/(0.05)`

`x = 3100`
