Thank you We sneak in and here's your smoke to

00:05

your brought to you by car dealerships and you thought

00:08

peer pressure was tough All right alexis owns a car

00:10

dealership On average she sells a car to six sevenths

00:13

of the customers who she meets in person If she

00:17

sold twenty four cars last week then how many customers

00:20

did she meet in person and here the potential answers

00:27

So alexis owns car dealership Good for alexis and her

00:30

father told her she'd never amount to anything She's selling

00:33

a car Two six seven silver customers In other words

00:35

she's sweet talking six out of every seven potential buyers

00:38

into driving off a lot in a new ride That's

00:40

Pretty decent rate We have to assume he's really good

00:43

at getting out of parking tickets too Now a question

00:46

wants to know at her average rate of sale How

00:48

many customers did she meet in person if she sold

00:51

twenty four hearts So the easiest way to deal with

00:53

a problem like this is yeah just throw out the

00:55

ratio with proportion Well we know that for every six

00:58

customers who bought a car there was one who said

01:01

nothing of twenty four of them cave How many were

01:05

unimpressed We can say that six is this seven equals

01:09

twenty four over something and we'll cleverly call that something

01:13

acts rather than something And alec and cross multiply six

01:18

times X equals twenty four times seven Got it while

01:21

twenty four seven hundred sixty eight Six x equals one

01:26

hundred sixty eight and we divide both sides by six

01:30

Got acts on this side and then six sixteen well

01:34

with over x equals twenty eight Don't make sense If

01:39

you think about it you alexis get six yeses to

01:42

everyone No then when she has four times as many

01:46

yeses twenty four should have four times as many nose

01:50

and indeed she does So our answer is c twenty

01:53

eight but don't let alexis persuade you otherwise She'll talk 00:01:56.598 --> [endTime] you into choosing d we just know it
