В театральном зале 364 мест. Количество свободных мест перед спектаклем составило четвертую часть занятых мест. Сколько денег заработал театр,если один билет стоит 20 леев?

364 - 100%.
1/4 свободно, значит, 3/4 занята.
3/4 - это 75%.
Чтобы узнать количество зрителей умножим 364 на 0,75.
364*0,75=273.
Чтобы узнать заработок театра умножим количество зрителей на стоимость билета.
273*20=5460
