An hour befor show time,only 155 people are seated for rockfest.According to ticket sales 95% of the people have yet to arrive

Ludmilka [50]

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

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

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

$x = 3100$

1/3 cup of flour is used to make 5 dinner rolls. how many cups of flour are needed to make 3 dozen dinner rolls

MAVERICK [17]

F = Cup of flour

D = Dinner roll(s)

12 = A dozen

36 = Three dozen

---------

1/3 * F = 5 * D

n * F = 36 * D

------

$\frac { 1 }{ 3 } F=5D\\ \\ 3\cdot \frac { 1 }{ 3 } F=3\cdot 5D\\ \\ F=15D$

$nF=36D\\ \\ n=\frac { 36D }{ F }$

This means that...

$n=\frac { 36D }{ 15D } \\ \\ n=\frac { 36 }{ 15 } \\ \\ n=\frac { 3\cdot 12 }{ 3\cdot 5 } \\ \\ n=\frac { 12 }{ 5 } \\ \\ n=\frac { 10 }{ 5 } +\frac { 2 }{ 5 } \\ \\ n=2+\frac { 2 }{ 5 }$

And this means that two cups of flour and 2/5 of a cup of flour are required to make 3 dozen dinner rolls.
