Хоккейные коньки стоили 4500 рублей . Сначала цену снизили на 20% , а потом эту цену повысили на 20% . Сколько стали стоить коньки после повышения цены ? Запишите решение и ответ.
I'm going to google translate this.
"Hockey skates cost 4,500 rubles. First, the price was reduced by 20%, and then this price was increased by 20%. How much did skates cost after the price increase? Write down that decision and answer."
4500 was reduced by 20%, so now there's only 80%. 4500*.8 = 3600
Then it was increased by 20%, so it's 120% of the total. 3600*1.2 = 4320.
I hope this helped. :))
