Answer 2

So 50.5 square feet costs $2,398.75

this is without installation right?

Answer 3

yep

Answer 4

I am really stuck on finding out how much it is per square foot

Answer 5

let x = cost per square foot

(# of square feet)*(cost per square foot) = total cost w/o installation

(50.5)*(x) = 2398.75

solve for x

Answer 7

divide both sides by 50.5

Answer 20

Answer 21

I'm guessing you aren't able to contact the teacher at all?

Answer 22

Answer 23

and they give u huge ones to I still have two more questions till im done

Answer 24

I see

Answer 25

this problem again right?

Answer 26

pretty much its just the dude took 4 hours to do it with installation what is the dudes rate per hour for the installation

Answer 27

cost with installation: $2,541.75

cost without installation: $2,398.75

Answer 28

the installation cost is the difference of the two

Answer 29

basically you ignore the cost of the material (the granite)

Answer 30

he did it with installation

Answer 31

they just wanna know what his rate per hour for the installation he took 4 hours

Answer 32

the 2500 figure is material + labor

Answer 33

you have to buy the material either way

the first option is buying the labor too

Answer 34

yeah just more money cuz he installed whatever it is called installation lol

Answer 35

what is the total cost of his labor?

Answer 36

it's not 2541.75

Answer 37

the liget question is The installation of the granite took the contracter 4 h. What is the contrctor's rate per hour for the installation? show your work.

Answer 38

if he only worked 4 hrs and got 2541.75 for it, then he'd be paid 635.4375 dollars an hour...yikes (that's on par with a high paid lawyer)

Answer 39

geezus these people are hella rich

Answer 40

thanks again tho

Answer 41

no the answer isn't 635.4375 or 635.44

Answer 42

I'm pointing out how really ridiculous and unrealistic that answer would be

Answer 43

you need to find the total cost of his labor alone (not including the cost of the granite material)

Answer 44

well its a serious unrelistic question nobody pays that much LOL

Answer 45

cost of his labor = (Total cost WITH installation) - (total cost WITHOUT installation)

cost of his labor = ???

Answer 46

are we dividing both sides again

Answer 47

urgg divide it by what? lol cant wait till this assigniment is over

Answer 48

what is Total cost WITH installation equal to?

Answer 49

2541.75

Answer 50

how about without installation?

Answer 51

2398.75

Answer 52

subtract the two and you get what?

Answer 53

143.

Answer 54

that is the total cost of his labor for 4 hours

Answer 55

now you divide by 4

143/4 = 35.75

Answer 56

thats realistic now lol

Answer 57

So he is paid $35.75 an hour

Answer 58

yes

Answer 59

your a math genius seriously lol

Answer 60

thanks :D
