Answer:

D. 504

Step-by-step explanation:

Let the number of days = x

Now, the number of students doubles each day for the two weeks with the initial number of students having measles = 8.

So, we have,

Days (x)                  Cases doubled                      Number of Students

1                                       8                                                8

2                                      8 × 2                                         16

3                                      16 × 2                                        32

4                                      32 × 2                                       64

So, we get the geometric series as 8, 16, 32, 64,...... for two weeks.

Then, the common ratio = \frac{16}{8}=\frac{32}{16} = 2

Thus, Number of students = 8\times \frac{(1-2^6)}{1-2}

i.e. Number of students = 8\times \frac{(1-64)}{-1}

i.e. Number of students = 8\times \frac{(-63)}{-1}

i.e. Number of students = 8 × 63 = 504

Hence, the number of students having measles at the end of the 6th day are 504.

12 = r - (34 - 2)
subtract he 2 from 34

12 = r - (32)
add 32 to each side

r = 44

Check:

12 = 44 - (34 - 2)
12 = 44 - 32
12 = 12 :)
