Answer 6

I've tried learning chinese
math is easier, trust me

Answer 7

LOL

Answer 8

anyways, let the variable "x" be "each desk"

Answer 9

lol I'm thinking about taking Japanese as my foreign language lol, I pretty good with Asian languages

Answer 10

Revenue = (revenue from each desk) * ("each desk")
can you replace the stuff I put in the parenthesis with numbers and variables? :)

Answer 11

ok

Answer 12

6000=450*150 (cross my finger)

Answer 13

ahh I forgot the variables

Answer 14

haha don't over complicate it ^_^
you just need one number and one variable

"the revenue from each desk will be $450"
"variable "x" be "each desk""

Answer 15

Revenue = (revenue from each desk) * ("each desk")

Answer 16

450(x+150)

Ahh I'm horrible at this stuff....

Answer 17

closer! :)

just No +150 part

try again?

Answer 18

450(x+y)
or
450(x+6000)

Answer 19

just remove the stuff after the plus all together ^_^

Answer 20

450(x)

Answer 21

yes! :)
that's for Part 1 ^_^

Answer 22

Wow now I feel dumb lol

Answer 23

no need to feel dumb :P
the wording can be confusing at times ^_^

Answer 24

lol my only issue is word problems, my professor pokes fun at me for that arg lol

Ok so the answer for "a." is 450(x) or is that the equation?

Answer 25

R(x) = 450 x

Answer 26

ahh ok so straight up 450x or just 450 by itself

Answer 27

450 x

Answer 28

OMG, so the answer was staring me in the face 0_o

Answer 29

indeed ^_^

now for the second part
Cost = (cost of constructing each desk) * ("each desk") + (cost of equipment)

Answer 30

150(450)+6000

Answer 31

so close! :D
change 450 to x

Answer 32

150(x)+6000

Answer 33

there you go ^_^

Answer 34

ok so I multiplied 150 to x, then divided 6000 by 150x and x=40

Answer 35

not quite
450x = 150x + 6000 solve for x

Answer 36

to get part 3

Answer 37

wait so 150x+6000 was the answer to "b"?

Answer 38

yes

Answer 39

AH ok
now I start solving I see lol

Answer 40

so the answer is 20

Answer 41

or x=20
