Answer:

x = 99°

Step-by-step explanation:

first: find the supplement to 123°:

180 - 123 = 57°

second: since all triangle interior angles total a80°:

180 - 42 - 57 = 81°

third: x = the supplement to 81°, so, x = 180 - 81 = 99°

As we can see from the table there is a pattern to the whole data in the table. A closer look reveals that when we multiply the number of students, n by the cost per student, c we get a constant number, 72. Let us see what we mean here:

  1. 3\times24=72
  2. 6\times 12=72
  3. 9\times 8=72
  4. 16\times 4.5=72

Thus, the function which models the data is the nc=12.

Now, let us move on to the next part of the question:

If 12 students go on the trip then the cost per student as per this model will be:

\frac{72}{12}=6 dollars=$6

Therefore, out of the given options, the option the correct option is number B.
