Follow the pattern. How many million bacteria were in the dish at

1 p. m. and 12 p. m.?

Hour Number of Bacteria (in millions)

12 p. m.

✓ DONE

1 p. m.

2 p. m.

3 p. m.

4 p. m.

32

6 p. m.

64

5 p. m.

Step-by-step explanation:

Given the information on the table

We are to follow the pattern to determine how many million bacteria were in the dish at  1 p.m. and 12 p.m.

Now:

It therefore means that the bacteria population doubles every hour. Following this pattern and reducing the exponents by 1 backwards, we have:

Therefore:

40% off the regular price is the correct answer.

step-by-step explanation:

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
