Question 1009585
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
<pre>With 1<sup>st</sup> reduction being 25%, price of car = .75 [(1 - .25) * 1]
2<sup>nd</sup> reduced price: .6 [(1 - .2) * .75]
With final reduced price being .6 (60% of original price), total reduction is: 1 - .6, or .4, or {{{highlight_green(40)}}} %
