So what you want to find is: what number times 120% is $324.00. (IT is 120% percent because it is the original <em>plus</em> 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!
Well, a Centimeter is 10 times bigger than a Milimeter.
So we can convert 9cm by multiplying it by 10
9 × 10= 90mm
SInce we know the length and width of the rectangle, we can now find the area of it, or "the space inside".
Area = length × width
Area = 90mm × 81mm
Area = 7290mm
