depends on the type of question. if it's a yes/no question (in other words it requires only a yes or no for an answer), then you use the word -ma (this is toneless) at the end.

there are other type of questions, (like when, who, what, how)....these questions have their chinese counterparts

what - shenme

how - zenme

when - shenme shihou (what time)

who - shui (second tone)

these words are easily recognizable as question words, and there are tones on the first part of each word (everything but the -me part)

add the numbers together: 9+3+11 = 23

you want the ratio of total number of grapes to total number of fruits

this should be consistent no matter how many fruits you have, so:

9/23 = x/161

cross-multiply and solve for x (number of grapes in a total of 161 fruits)

23x = 9*161 ---> x = 63

okay, that's an upside-down U and the maximum value is at the top 

if you put the function in vertex form you can easily find the vertex:

group the first two terms and factor out the negative (essentially factoring out -1):

p = - (x²-14x) + 54

complete the square by taking the middle coefficient (14), dividing it by 2, squaring it and adding the result to the terms in parentheses

p = -(x²-14x+49) + 54 + 49  (we've really subtracted 49, so we have to undo this by adding 49)

p = -(x-7)² + 103

the vertex is at (7,103), so your maximum profit is $103

range value is the y value

domain value is the x value

(a) find y when x = 0   

 y = 2x-1 = 2(0)-1 = -1

y = -1

(b) find x when y = 5

5 = 2x-1

6 = 2x

x = 3

Cost = $31/$1000  *  $24000 = $744

Quarterly payment = $744 / 4 = $186
