00:15

friday His total is never more than twenty bucks including

00:18

the untaxed five dollars delivery fee and a seven percent

00:21

tax on this food if f represents the cost of

00:24

his food which of the following represents jasper's order and

00:27

your potential answers All right okay That taxes here for

00:32

jasper the life of a single man every friday A

00:35

sad nagging reminder of his loneliness Nothing He needs someone

00:39

else to make him feel whole But well it's really

00:41

hard to finish an order Chicken fried rice all by

00:43

yourself Alright so every once in a while a problem

00:46

comes along we can zip through in a matter of

00:47

seconds and this is one of them Let's check out

00:49

our answer choices here We're told that there's a seven

00:52

percent tax on jasper's food represented by the variable f

00:56

well there's no reference to that seven percent tax and

00:58

option c so that was clearly a loser We're also

01:01

told that five dollars delivery fee is untaxed and yet

01:04

both options a and b have the delivery feet included

01:08

inside the parentheses and then they haven't multiplied by either

01:11

point Oh seven or one Point Oh seven neither of

01:13

which could possibly be right Since that five bucks has

01:16

to stand alone and lickety split Just like that we

01:19

determine that option Do one point Oh seven f plus

01:22

five is less than twenty has to be the right

01:25

answer process of elimination Yes we've got the cost of

01:29

the food being multiplied by one point Oh seven and

01:31

that's one hundred percent plus percent extra Plus the five

01:34

dollars delivery charge must equal or be less than twenty

01:37

bucks Yes is it was outlined in the problem Jasper

01:40

has resolved to get back into the dating scene starting

01:43

next week We wish him the best of luck Perhaps

01:45

someday soon his fortune will read his cheaper to go 00:01:48.808 --> [endTime] split seas
