I need help with this question:The price of a car is reduced by 25 percent. the new price is reduced by a further 20 percent. the two reductions together are equal to a single reduction of what percent? 45 is a wrong answer , my teacher said that
\n" ); document.write( "
With 1st reduction being 25%, price of car = .75 [(1 - .25) * 1]
\n" ); document.write( "2nd reduced price: .6 [(1 - .2) * .75]
\n" ); document.write( "With final reduced price being .6 (60% of original price), total reduction is: 1 - .6, or .4, or \"highlight_green%2840%29\" % \n" ); document.write( "
\n" );
