Автор ответа: TheLittleMermaid

Сначала посчитаем и вычтем из общей суммы количество проживающих в городе детей и подростков:

500,000 - 100%
Х - 15%

$\frac{500000*15}{100}$ = 75,000 (Дети и подростки)

500,000 - 75,000 = 425,000 (Все остальные: взрослые, пенсионеры и т.д)

Ищем количество неработающего населения:

425,000 - 100%
Х - 25%

$\frac{425000*25}{100}$ = 106,250 (Неработающее население)

Дальше уже все просто:

425,000 - 106,250 = 318,750 (Работающее население)

Ответ: 318,750

500000/100=5000 (1%)

5000*15= 75000( детей и подростков)
500000-75000= 425000(рабочее население)
425000/100=4250(1% из рабочего населения)
4250*25= 106250( 25% не рабочих)
106250+75000= 181250( общее кол-во не рабочих)
500000-181250= 318750 ( рабочее население)

Scheduling a News Conference

The conference should be scheduled at а time that is convenient for the

reporters — that is, with an eye on the deadlines of the media represented. In

general, mornings or early afternoons аrе best for both print and broadcast

media. This allows sufficient time for reporters to get stories in the next

morning’s daily or on the 6 p. m. news. If the primary audience is the trade

press — reporters rерresenting publications in а particular industry — late

afternoon news conferences may be more convenient.

You should avoid Saturdays and Sundays, as well as major holidays. Most

media operate with skeleton staffs on these days and hence don’t have the

personnel to cover news conferences.

Another consideration which often can’t be planned for, is to schedule

the news conference on а day when there aren’t а lot of conflicting news

events. It’s always wise to avoid election days, for example.

Selecting а Location

А location for а news conference must meet several criteria. First, it must

be convenient for the media invited and relatively close to their places of

work. Second, the room selected must have the necessary facilities to

accommodate both print and broadcast media.

Organizations often use hotels and conference centers for news confe

rences, as well as the corporate headquarters. It is important for the room to

have plenty of electrical outlets, particularly for radio and television news.

Television people may prefer а room on а ground floor near an entrance so

that they can park а mobile communications centеr outside the room. In

some cases, they will want to run cables from the truck to the room for live

broadcast.

You should make the room available оnе or two hours in advance so that

radio and television crews can set up. Have а general seating plan to make

sure that the equipment doesn’t obstruct the view or hinder the work of the

print reporters. An elevated platform for ТV cameras in the back of the room

is helpful.

Another consideration is to have several smaller rooms reserved nearby

for print and broadcast reporters to conduct an exclusive interview with а

company representative after the general news conference.
