Let's see what it would take to win that trip to Hawaii. Remember that you think you'll respond to 12 questions and hope to score 600 points to win,
although it's possible to score even more points or many fewer (including negative scores!) on
the show.
Here are the equations you wrote to model your winning scenario:
x+y=12
100x - 200y = 600
Are the boundaries of the first equation viable in the second equation? What does this
suggest about your plan to score 600 points?
Select the two correct statements.

No

              At least 10 correct answers and no more than 2 wrong answers.

Step-by-step explanation:

Are the boundaries of the first equation viable in the second equation?

The boundaries of x + y = 12 are: (0, 12) & (12, 0)

Input those solutions into 100x - 200y = 600 to check for true statements:

               x        y             100x - 200y      

(0, 12)       0         12           100(0) - 200(12) = -2400 ≠600    <-- not viable

(12, 0)      12         0            100(12) - 200(0) = 1200 ≠600     <-- not viable        

The boundaries of the first equation are possible scores but NOT valid in the second equation.

Solve the system of equations:

100x - 200y = 600   →   1(100x - 200y = 600)   →   100x - 200y =   600

      x +  y =   12         →  200( x + y = 12)             →  200x + 200y = 2400  

                                                                                300x              = 3000

                                                                                                   x = 10

Input x = 10 to solve for y:

x + y = 12

10 + y = 12

       y = 2

You must get 10 correct answers and 2 wrong answers to achieve a score of exactly 600.

If you get more than 10 correct answers, your score will be greater than 600 and you would still win.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

d is the answer
