or this shit is getting harder

If Costas buys oranges at 5 for 2 cents and sells them at 4 for three cents, how many must he sell to make a profit of 420 cents?

anyone???

First you find a common denominator:

buys 5 oranges @ 2 cents

sells for 4 @ 3 cents

so it becomes buy 20 @ 8 cents

sell 20 @ 15 cents

7 cent profit

x 60 oranges = 420 cents.

I hate to correct, but it's 60, not 600

dont you have to find the common denominator of these two numbers also?

so wouldnt it be 6 instead of 8?

or do i fail 2nd grade math again?

(2/5) and (3/4) = (8/20) and (15/20)

I'm in transform math, the next step past calc2, its a pain in the ass

numerator just means the top part of the fraction
in this instance the fraction represented a ratio. that made it easier to solve for me.

Z transforms are used in signal processing. Converting analog signals to digital and then back to analog. Everytime you listen to music on a cd player, hear an amplifier, listen to a MP3, watch a DVD, there are tons of Z-transforms going on :)

if you changed "apples" to "grams of weed" and "cents" to "billz" im sure most of the AZHT community to figure it out much easier.
