Объяснение:

х - цена лыж.

Цена лыж летом:

(100%-10%)·x/100%=0,9x

Цена лыж зимой:

(100%+10%)·0,9x/100%=1,1%·0,9x=0,99x

x-0,99x=0,01x; 100%·0,01x/x=1%

READING Task 2. Read an article and complete the tasks.
Cook your way to a better life
A. When he was fourteen, his ambition was to run a pub, just like his dad. But in the last twenty years, celebrity chef Jamie Oliver has achieved far more. With a chain of restaurants, a number of popular television series and bestselling cookery books. Jamie Oliver is a well-known name in every UK household. I’m a huge ‘Jamie fan’. I admire his passion for improving the food we eat and helping people change their lives.
B. Jamie’s first project, Fifteen, in 2002, aimed to help young people. He took fifteen unemployed young people, with no previous experience of cooking, and trained them to be top-class chefs in his restaurant, also called Fifteen. I remember one trainee, Lloyd Hayes. He left school with no qualification and started getting into crime. But the project worked and Lloyd got a good job as a chef in a top London restaurant. I heard recently that in the future he is going to teach people to cook professionally. I think it’s this kind of success story that makes Jamie and his project so special.
C. Another special project is Jamie’s Ministry of Food which he started in 2008. There are two aims: firstly, to teach people how to cook healthy, affordable food instead of eating fast food; secondly, to set up the Pass It On scheme: encourage each person to pass on a recipe they learned to four other people. Those four people then teach four more people, and so on. Thousands of people have changed their cooking habits as a result –and I’m one of them. I’ve decided I’m not going to eat fast food anymore. I’m going to cook for my friends and take time to eat good food.
D. It’s not adults, but children, too. Jamie’s School Dinners, one of Jamie’s best-known projects, tried to improve food in schools and encourage children to eat well. It was difficult to convince some of the children, but in the end, many schools improved their menus. And my children are going to eat their vegetables now! So, What’s Jamie going to do next? Well, whatever it is, one thing is for sure, I’m going to miss it!
A. Choose in which areas has Jamie Oliver made a difference to people’s lives.
a. training chefs in restaurant 1.____ [1]
b. working with doctors and hospitals 2.____ [1]
c. giving food to homeless people 3.____ [1]

4. When he was a young, Jamie Oliver wanted to manage a ______. [1]
