Aschool auditorium has a seating capacity of 800. for an upcoming event tickets cost $6 for adults and & 4 for students. at last years play, three times as many students attended as adults. if the attendance at this years play has a similar ratio how many will be earned if the auditorium is filled to capacity?

Answer:

$3600 will be earned , if the auditorium is filled to capacity

Step-by-step explanation:

Given:

Seating capacity of the school auditorium =  800

Cost of Adult tickets  = $6

Cost of Student  tickets  = $4

Three times as many students attended as adults

To Find :

Amount that will  be earned if the auditorium is filled to capacity = ?

Solution:

Let

The number of students be s

the the number of adults be a

then

Three times as many students attended as adults

Number of students  = 3  x number of adults

s = 3a

Total number of seats or tickets that can be sold  = 800

so

s + a = 800

3a+a = 800

4a =800

a =

a= 200

So the number of adult = 200

Number of children = 3a = 3(200) =600

Now total amount earned  =

=>(Number of adults X cost per adult ticket) + (Number of children X cost per children ticket)

=> (200 X 6) + (600 X 4)

=>(1200) +(2400)

=>3600

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
