Ответ:

      8

Объяснение:

1) 100% + 10% = 110% - составляет новая цена от старой

2) 110% = 1,1

3) 110 · 1,1 = 121 (руб) - новая цена

4) 1000 : 121 = 8 целых и 32/121  - количество билетов на 1000 руб

Так как количество билетов выражается целым числом, то 8.

A relatively new addition to the age-old tradition of global, national and local festivals, the
Shopping Festival, or the DSF as it's more commonly called, is an event that offers some
everyone. It lasts for about a month, and takes place in one of the winter months every year.
What first began as a tourist attraction in 1996 is now a celebration of buying and selling the
welcomes hundreds of thousands of visitors. Over 2.300 shops offer an enormous variety of goods
at very low prices. Festival-goers will find even more bargains at one of the most popular
attractions of the DSF, the Night Souk. This is a big street market that is open from the aftemoon
the small hours of the morning. There, it is customary for the shoppers to haggle with the sellers
over the price of something, until both the buyer and the seller agree on a satisfying price
But the DSF is not only about shopping. There is a wide range of activities that keep everyone in
the family happy. Over the years, events such as a food festival, fashion show carnival and a
fireworks display have offered visitors an enjoyable experience. The festival organisers keep
surprising visitors with new, bigger and better events every year.
The Dubai Shopping Festival is a fantastie family event that combines shopping with fun and
culture, and brings people from the four corners of the world together. As the slogan of the festival
says: "One Family, One World, One Festival".
