[MUSIC] In the previous interviews, the survey questions didn't ask anything about people's favorite brand of chocolate, just whether they liked premium chocolate. Were you surprised about that? Notice the expressions we used to talk about frequency. Something happens, and also price. Once, means one time. Twice, means two times. After that, we say three times a month or four times a month. To show that we're just estimating, we say, about. This means that this is not exact. We also use adverbs of frequency like usually, or always, or almost never to talk about how often something happens. Every day means all the days. Every other day or every two days, means that you skip a day or maybe two days. You can also say, every other week or every two months, or every other year to show that something alternates. For example, you do something one week but not the next week. Notice the vocabulary related to price. We say, it cost ten dollars a box, or I spent four dollars for each bar. If you want to empathize the individual item in a more formal business setting, or in a price list, we use the word per to mean for each item. Two dollars per bar. It's often difficult to hear the difference between numbers like 13 and 30. 13, usually has stress on the second syllable, if you can remember this, it's because the three is in the second position in the number. You can hear that T, sound, because the syllable is stressed, 13. 30 has stress on the first syllable, so you hear the sound thir, clearly. But you have a softer sound for the T. It's kind of between a T and a D. 30. Which number do you hear? Repeat and see if you were correct. 40. 40 cents. 16 people. $17. 18 times. $90. Here's some ways that we express a limit. >> I sometimes pay up to $5 a package. I never spend more than $4 on coffee. The most I spend is $10 a week. >> So again, as you've seen above and in many examples in this lesson, we use about to show that in amount or frequencies not exact. For example, you can say, I go about once a month and I spend about $30. We also give a general estimate by expressing a range. When we write a price range, we put the currency symbol, like the dollar sign, before each amount. But, when we talk, we only say the word dollars one time. >> I spend between three and four dollars. >> The word somewhere and anywhere in this case, just emphasize that there is a range. >> It costs somewhere between twenty and thirty dollars. I pay anywhere from ten to fifteen dollars. >> Notice that we say, between X and Y, but from X to Y [MUSIC]
