All right t s i master members would get a

00:04

little word problem for you Here we go Tickets for

00:06

a play cost four bucks for each child and eight

00:09

fox for each adult If there are only twenty children's

00:11

tickets sold which of the following equations could model How

00:15

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
