The value of a professional basketball player's autograph rose 20% in the last year. it is now worth $324.00. what was it worth a year ago?

So what you want to find is: what number times 120% is $324.00. (IT is 120% percent because it is the original plus the new percent) Simply set it up like so:

SN *120% = $324.00

Now turn the percent into a decimal:

SN * 1.20 = $324.00

Now divide $324.00 by 1.20

SN = $270

The original value of the basketball player's autograph was 270 dollars!

Hope that helps!
