Answer 1

"A store buys an item for $x and sells it for $y. Write expressions for the markup and the % of the markup" I need some quick help. I don't really understand this. It's the percent of markup * store's cost

Answer 2

so.... what do you need help with anyway?

Answer 3

@jdoe0001 I need help on the problem in quotations.

Answer 4

well...do you know what markup is?

Answer 5

Yes, markup is adding the sales price plus the percentage off as far as I know.

Answer 6

if you put a lemonade stand
and say you bought the lemons for 10cents

if it takes say 5 lemons to make a glass of lemonade, your lemons cost is 10cents 5 times or 50cents

would you sell it at 50cents? well...you put work in it...so you charge for that

say you sell the glass of lemonade for 75cents
so you're adding 25cents more to the costs of 50cents

that ADDED amount, to acccount for your work, is the so-called "markup"

Answer 7

or "profit" if you wish to call it so
are you supposed to make your own expression with a made up cost? like say... you'd make up your own number of a product on how much it cost you and how much you'd add to it in price?

Answer 8

I am pretty sure we have to just write the expression using the variables, if that helps. @jdoe0001

Answer 9

hmmm well... if we call the markup say "m"

then we get the item for "x" price and we sell it for x + m

so one can say the selling price "y" is y\(\bf = x + m\)

in percentage terms... if "m" happens to not be some constant, but a percent of "x"

then that'd be \(\bf y=x+\cfrac{m}{100}x\implies y=x+0.0mx\)

Answer 10

Okay thank you @jdoe0001 ! I can figure it out from there!
