much total money Why is made in ticket sales They're
- 00:23
asking us to make an equation that model's this so
- 00:26
it can scale for a hundred kids a thousand kids
- 00:29
whatever It's smart of the theater to restrict the number
- 00:31
of children attending the plate a twenty impromptu screaming has
- 00:35
never made a performance more enjoyable when writing equations be
- 00:38
sure to follow the units Why is to find is
- 00:40
the total amount of money made in ticket sales so
- 00:42
both terms on the other side of the equation should
- 00:45
be also in terms of money Ex isn't defined but
- 00:48
it must represent the other unknown value in the situation
- 00:52
Whatever that value turns out to be right it's going
- 00:54
to be some number of tickets all right so let's
- 00:56
work with what we do know For now we got
- 00:58
to type two tickets that are sold the ticket price
- 01:00
that four bucks for brad kids and a ticket price
- 01:02
it eight bucks for adults and the total income comes
- 01:05
from the combined sales of both combined right We're going
- 01:08
to have four times something in eight times something so
- 01:11
we got total income equals income from children's tickets plus
- 01:15
income from adults tickets or while total income we're just
- 01:18
going to call why income is always found by multiplying
- 01:21
the price of the item by the number of units
- 01:23
sold We know that twenty children's tickets are sold but
- 01:26
we don't know how many adult tickets are sold Ah
- 01:28
ha something we did not know well acts must represent
- 01:31
the number of adult ticket sales especially because it's multiplied
- 01:34
by eight cost of one adult ticket in every answer
- 01:37
choice So why is the income from children's tickets plus
- 01:42
eight x and there are twenty children's tickets sold than
- 01:45
the each cost four bucks so total income from those
- 01:48
sales is a fixed eighty dollars right four times twenty
- 01:51
there So why is the income from children's tickets plus
- 01:55
eight x So what the answer Well why eagles eighty
- 01:58
plus eight x yeah addition is commuted If so it's
- 02:01
okay to reverse the order of the terms on the
- 02:03
right side of the equation and you have the answers
- 02:05
day and enjoy the met Neither the floor's all sticky 00:02:09.445 --> [endTime] here
