Answer 1

To determine how many video tapes Lance will have left in month 7, we can first look at the pattern of how many video tapes he has sold each month.

From the table:

- Month 4: 32 video tapes
- Month 5: 28 video tapes
- Month 6: 24 video tapes
- Month 7: ?
- Month 8: 16 video tapes

Now, let's find the difference in the number of video tapes from one month to the next:

- From Month 4 to Month 5: 32 - 28 = 4 video tapes sold
- From Month 5 to Month 6: 28 - 24 = 4 video tapes sold

This shows that Lance is selling 4 video tapes each month consistently.

Continuing this pattern, from Month 6 to Month 7, we can subtract 4 from 24:

24 - 4 = 20 video tapes left in Month 7.

Finally, we examine the choices:

- A. 3
- B. 12
- C. 16
- D. 20

The answer is **D. 20**.
