Question

it took me forever to solve a problem similar to this, you try it:


In a recent year, the total sales at store A were $250,000 more than at store B. Total sales at the two stores were $600,000,000. What were the sales at each store.

Answer 1

oh my bad

Answer 2

haste is waste lol :P

Answer 3

ts = b + a

a = b + 250,000

600,000,000 = b + (b + 250,000)

600,000,000 = 2b + 250,000

600,000,000 - 250,000 = 2b

599,750,000 = 2b

store b = 299,875,000

600,000,000 - 299,875,000 = store a

store a = 300,125,000

Answer 4

Answer 10

OMG

Answer 11

let me see it again

Answer 12

I keep doing different problems to see if I have the concept down, but I don't know where I am going wrong.

Answer 13

ummm i dun see anything wrong with lilg has done to be truthful fionaJ.. it seems pretty correct :O

Answer 14

are u sure the answer is correct?

Answer 15

the numbers r big so maybe an error in addition is possible, but the concept is correct.. do u get the concept?

Answer 16

not really.. "/

Answer 17

um ok.. can u see the solution given by lilg the big one.. in that which step did u not comprehend?

Answer 18

Pardon me, I do understand the concept. I just dnt understand how the answer is always wrong when I follow every step !

Answer 19

ok lets solve this together now..let the sales of store A be a and that of store B be B

Answer 20

now we have the sales of A where 250000 more than b

so the equation is a=b+250000

Answer 21

then it is given the total sales of A and B were 6000000

so we have a+b=600,000,000

Answer 22

now lets substitute the first equation in second we have

b+250000 + b=600,000,000

Answer 23

umm you get it till here?

Answer 24

fionaJ?

Answer 25

fionaj unfortunately YOUR answer is incorrect

a way to check your answer is

remember store a got $250,000 more sales then store b

so to check if your answer is correct you add 250,000 to store b's sales

and it should be the same as the answer for store a

another way to check is to add both store a and b together you should get
600,000,000

as you can see with your answer

B=299,862,500 and A=300,137,500.

store b = 299,862,500

299,862,500 + 250,000 = 300,112,500

that is not the same answer as you got for store A

hence why your answer is incorrect

:) dont forget to click good answer

Answer 26

- excuse me as I had an emergency to tend to, but I have put this dwn into my notes, thank you all so much. I understand it now.

Answer 27

And I answered this on one of my reviews and your answer, which was MY answer as well, is incorrect.

Answer 28

I think your slightly confused fionaj
your answer that YOU wrote was

B=299,862,500 and A=300,137,500.

My answer that I wrote was

store a = 300,125,000 store b = 299,875,000

what was the correct answer then if you say my answer was incorrect?

Answer 29

My answer was simply what you had but the computer generated review was B=299,862,500 and A=300,137,500.

Answer 30

well to check which answer is correct you need to remember store A got $250,000 more sales then store B.

which would mean

299,862,500 + 250,000 = $300,112,500 (As you can see thats not the same as your answer for store A which means it is wrong)

or have i misunderstood the question?

Answer 31

?

Answer 32

You have not misunderstood the question, Im on your side with this problem by all means. I was just allowing others to see what I was going through when I solved the problem. I got the same answer as everyone else, the correct answer tht was on the review threw me off.

Answer 33

ok i get it now lol
