much total money Why is made in ticket sales They're

asking us to make an equation that model's this so

it can scale for a hundred kids a thousand kids

whatever It's smart of the theater to restrict the number

of children attending the plate a twenty impromptu screaming has

never made a performance more enjoyable when writing equations be

sure to follow the units Why is to find is

the total amount of money made in ticket sales so

both terms on the other side of the equation should

be also in terms of money Ex isn't defined but

it must represent the other unknown value in the situation

Whatever that value turns out to be right it's going

to be some number of tickets all right so let's

work with what we do know For now we got

to type two tickets that are sold the ticket price

that four bucks for brad kids and a ticket price

it eight bucks for adults and the total income comes

from the combined sales of both combined right We're going

to have four times something in eight times something so

we got total income equals income from children's tickets plus

income from adults tickets or while total income we're just

going to call why income is always found by multiplying

the price of the item by the number of units

sold We know that twenty children's tickets are sold but

we don't know how many adult tickets are sold Ah

ha something we did not know well acts must represent

the number of adult ticket sales especially because it's multiplied

by eight cost of one adult ticket in every answer

choice So why is the income from children's tickets plus

eight x and there are twenty children's tickets sold than

the each cost four bucks so total income from those

sales is a fixed eighty dollars right four times twenty

there So why is the income from children's tickets plus

eight x So what the answer Well why eagles eighty

plus eight x yeah addition is commuted If so it's

okay to reverse the order of the terms on the

right side of the equation and you have the answers
