00:05

jour brought to you buy groceries We're not sure why

00:08

we always get so philosophical Only talk about him Maybe

00:11

it's Because they're in day cards Yeah we want Sorry

00:16

lisa Grocery cart All right Serena makes three grand a

00:20

month If she spends g dollars on groceries each month

00:23

and what fraction of her monthly income does she spend

00:25

on groceries And here the potential answer is brought to

00:28

you by jenny craig Okay so we've got serena who

00:32

makes three grand a month So she's either a teacher

00:35

a tollbooth collector in california and this question wants to

00:38

know what fraction of her income she spends on groceries

00:42

were told to use g is the amount she spends

00:44

each month So really all this question is asking is

00:47

do we know how to take this information and express

00:50

it accurately to show what we're supposed to show To

00:53

wrap her head around this let's plug in a number

00:55

for a g Well let's say she spends three hundred

00:58

bucks a month on grocery Well we could go with

01:00

two hundred eighty four dollars ninety two cents but let's

01:02

Go easy on ourselves here If she spends three hundred

01:04

bucks a month on groceries and she makes three grand

01:07

a month well then she's spending ten percent of her

01:09

income right Well it makes sense but how do we

01:12

get that ten percent Well by putting three hundred our

01:15

g in a fraction over the three thousand when we

01:20

divide those two Numbers we arrive at point 1 or

01:22

ten percent So then our expression needs to be g

01:26

over three thousand answer a way Sure hope serena is

01:29

living rent free someplace Otherwise she may want to start
