subsitute 10 for x and re-read the problem

i can't believe i am so bad at math. I would never have solved this O_o

suppose you buy something for 0.8 dollars and u wanna make profit so u are gonna sell it for a higher price .Lets say u sell it for 1 dollar ..whats the profit u make?its 1-0.8 which is 0.2..taking a simpler ex u buy something for 1 $ and sell it for 2$ the profit is 2-1 =1$..so he makes 0.2x dollars per burger..number of burgers to a 40x buck profit would be 40x/0.2x(total profit/profit per burger) cuz the total profit he makes would be (number of burgers sold*profit per burger)

I knew the answer immediately. Percentages can become familar but I did not know the process. This helps me figure out how to apply it other places.

where did he get .2?

[smooth7]

think about it like this

P= x-.8x=40x

but think of the x as having a 1 in front like this 1x-.8x. this 1 is not written because it is understood. so 1-.8= .2

Therefore..

p= x - .8x= 40x

p= .2x = 40x and so we have to divide these to to solve for p

so we have..

p= 40x/.2x

p= 200x so 200 is your answer since x is the value in dollars and 200 is the amount of burgers being sold.

[darklodvinay]

lets say u have sold a burger u bought for 1$ for 2$ ..so your profit would be 1$ per burger ..how many burgers must to sell to make 50$profit ..\that would be 50 burgers rit?=)

[vladmire1981]

Hi I was wondering why is he making a profit of .2x how did he come up with this number? why not .3x or .4x

[PimpHN]

because he sells at X/each burger. Remember the invisible "1"...wich X should look like this:1X

Now, if his cost is .8, that means that 80% of what he earns went into getting that burger donde...

So the difference 1X - .8X = .2X

[josacra]

P(x-.8x)=40x

P= 40x/.2x

P= 400/2

P=200
