Answer 2

Think of two items that you can sell

Answer 3

iphone 4 and iphone 4s

Answer 4

iPhone 4s and Galaxy S3.

Answer 5

Answer 7

Answer 8

ok say x = number of iphone 4 models sold and y = number of galaxy S3 models sold

Answer 9

Do you want a cough syrup? lol.
Jk

Answer 10

ahaha and ok @jim_thompson5910

Answer 11

oh wait, i mixed up the two, one sec

Answer 12

ok

Answer 13

let x = cost of one iphone 4 model and y = cost of one galaxy S3

So if you sold 5 iphones at x dollars a piece, then you would earn 5x dollars

if you sold 2 galaxy S3's at y dollars a piece, then you would earn 2y dollars

In total, you would earn 5x + 2y dollars

Answer 14

is that the whoel part 1?

Answer 15

If you want that total to be at least $45, then you would say

Total ≥ 45

5x + 2y ≥ 45

Answer 16

ok thanks and part 2 i would

Answer 17

show me what you think you're supposed to do

Answer 18

no idea :(

Answer 19

pick any ordered pair you want

Answer 20

what ordered pair did you pick?

Answer 21

3,-1

Answer 22

make the second coordinate positive

Answer 23

so (3,1)

this means x = 3 and y = 1

Answer 24

yes

Answer 25

so the iphone is sold at $3 a piece and the galaxy S3 is sold at $1 a piece

Answer 26

plug it into 55x + 2y ≥ 45

Answer 27

ok so 55(3)+2(1) ≥ 45

Answer 28

oh wait, i meant to say

5x + 2y ≥ 45

Answer 29

5x, not 55x

Answer 30

OH i was like wtff

Answer 31

5(3)+2(1)≥45

Answer 32

is that true or false?

Answer 33

faalsee

Answer 34

so (3,1) is not a solution

Answer 35

do i keep going till i find one?

Answer 36

which means that making those prices will not get you $45 or more

Answer 37

truee

Answer 38

no you don't need a solution, you can just describe what (3,1) means to the problem

Answer 39

ok
