Question

together, a washer and dryer cost $750. If the washer costs $85 more than the dryer, what does each appliance cost?

Answer 1

@Nnesha ???

Answer 2

If the dryer costs $x (x dollars), how much does the washer cost?

Answer 3

I'm just having a hard time putting this into an equation...

Answer 4

x=x+85=740? I just don't see how to set this up..

Answer 5

Don't worry about the equation and don't think about math.
If I tell you that I have x apples and you have three more apples than I do, how many apples would you have?

Answer 6

I would have 3 more than you..

Answer 7

750 - 85 = x / 2 = y

Answer 8

does that help?

Answer 9

If I have 2 apples, then you would have 2+3 = 5 apples.
If I have x apples, then you would have x+3 apples.
If the dryer costs x dollars, then how much would the washer cost?

Answer 10

x+85

Answer 11

Right! Back to the apple example:
If I have 2 apples and you have 2+3=5 apples, how many apples do we have altogether?

Answer 12

7 apples

Answer 13

RIght! If the dryer costs x dollars and the washer costs (x+85) dollars, how much would the washer and dryer together cost?

Answer 14

whatever x is plus 85.. which is somehow 740...

Answer 15

OH WAIT IS MY EQUATION X+85=740???? IS IT THAT SIMPLE?

Answer 16

Very close:
The dryer costs x dollars
The washer costs x+85 dollars.
Adding together, we find the total price to be?

Answer 17

740..

Answer 18

I'm so confused

Answer 19

I meant the equation representing the total price.
In the apple example, I had 2 apples and you had 5 apples, so you said we have 7 apples. How did you get that number?
Applying that to this question, if the dryer costs x dollars and the washer costs x+85 dollars, how much would the total price be?

Don't think of x as a variable. What if x=0? If the dryer costs 10 dollars and the washer costs 10+85 dollars, how much would the washer+dryer cost together?

Answer 20

so just 85 dollars? I don't know how much the dryer is..

Answer 21

Think of x = (one box of 3 apples). If I have x boxes and you have x boxes, how many apples do we have in total? How many boxes do we have in total?

Answer 22

6

Answer 23

Right! I have x = (one box) of apples and you have x = (one box) of apples, so together we have 2x = (two boxes) of apples, which gives us a total of 6 apples. Do you see what I'm getting at here?

Answer 24

I think so......

Answer 25

Don't think of x as some foreign thing. It's just a placeholder for a number. If x=1, then x+x is the same as 1+1 which equals 2.
Back to your question:
If the dryer costs x dollars and the washer costs x+85 dollars, then what equation gives you the total price?

Answer 26

x+85(2)=740??????

Answer 27

Dryer (x) + Washer (x+85) = 740
That gets you x + x+85 = 740
Remember that you can combine your x's, just as you did when we thought of x as a box of apples.

Answer 28

this will get you the same answer....
x = washer
y = dryer

x + y = 740 -- washer and dryer cost 740
y = x + 85 -- dryer cost 85 more then the washer (x)

and just solve by substitution

but like I said, it is basically the same thing as the equation given by DisplayError ^^

Answer 29

this is what I got... the washer is $412.50 and the dryer is $327.00

Answer 30

yes? no?

Answer 31

@displayError @texaschic101

Answer 32

@Hero can you check my answer for me?

Answer 33

no. if you add them together it doesn't equal $750. 750 - 85 = ? /2 = ? is an equation for drier and the equation for the washer is 750 - 85 = ? /2 = ? +85

Answer 34

the drier*

Answer 35

ohhhhhhh okay this time I got the washer=417.50 and the dryer=332.50

Answer 36

correct.

Answer 37

yay!!! thank you so much for sticking around to help!!!

Answer 38

no problem. :D
