Fifteen note cards cost $4.80. How much does it cost to buy 8 note cards?

OpenStudy (anonymous):

$4.80/15 = .32 * 8 = 2.56

OpenStudy (anonymous):

I got $25.00

OpenStudy (anonymous):

hmmm.....

If you take 15 cards and multiply them by .32 = 4.80 so you know that the amount will be approximately 1/2 of that because the question on here says 8 cards would cost what. So 8 x .32 = 2.56

Oh I get it. Thanks!
