You can put this solution on YOUR website!
45 is incorrect because you have: the price of the car is 100% and it is reduced by 25%. 100-25= 75%.
\n" ); document.write( "Now you have a further reduction of 20%, but note, it's 20% off of 75%, not of the original full price of 100%.
\n" ); document.write( "-----------------------------------
\n" ); document.write( "75%-(75*20)= 75-15= 60% is the new price of the car, and 100-60= 40% is the total reduction in price.
\n" ); document.write( "
