money The graph below shows the price of nut box

00:23

with dollars on the horizontal axis and nut bucks on

00:27

the vertical axis The wife The exchange rate is something

00:31

nut bucks per dollar Thanks Not f***ed for gone nut

00:36

bucks I get a dollar bill All right Well first

00:39

of all this nicky nut place seems like a total

00:41

scam to us Uh hard earned us dollars in exchange

00:45

for nut bucks Really Guess they're appropriately named on lee

00:49

and nut is going to buy any of these things

00:51

huh So we've got a graph of a line and

00:54

we're told that the for rosana ll access represents dollars

00:58

This thing So this is two dollars four dollars and

01:01

so on And nut bucks or shown by the vertical

01:04

axis Two bucks for bugs No And we need to

01:07

find the exchange rate Something tells us a phone call

01:10

To our local currency exchange gonna do the trick So

01:15

what were sneakily being asked to find here is the

01:18

slope of the line point People people exchange rate is

01:22

really referring to slopes and small slope is a rate

01:25

change And that key word her should tell us that

01:28

we need to create a fraction well with nut bucks

01:30

on top and dollars on the bottom But we know

01:33

how many nut bucks is her dollar got it That's

01:36

what we're gonna do All right well we can pick

01:38

a sample point Say this one it's easiest to go

01:41

with this one since it's exactly one dollar and we

01:43

won't need to simplify our fraction Though it one dollar

01:46

were at three nut box we put the free over

01:49

the one and looks like the exchange rate is three

01:52

nut bucks per dollar So yeah three is our answer

01:56

Yeah it definitely seems like a rip off but at

01:57

least you can get something for your nut box We're

01:59

still trying to figure out what to do with all

02:01

those british fifty pound notes that we've had sitting in 00:02:03.886 --> [endTime] our sock drawer since last spring
