Answer:
- <em><u>12 tickets</u></em>
Explanation:
You must assume that the ratio of the number of tickets in row 7 is a constant.
That permits you to set a proportion with the ratio of the number of tickets in row 7 for the first batch of tickets and the ratio of the number of tickets in row 7 for the next 33 tickets sent out:
<u>1. Ratio of number of tickets in row 7 for the first batch.</u>
- Number of tickets in row 7: 20
- Total number of tickets: 20 + 19 + 16 = 55
- Ratio: 20/55
<u>2. Ratio of number of tickets in row 7 in the next 33 tickets sent out:</u>
- Number of tickets in row 7: x
- Total number of tickets sent out: 33
- Ratio: x/33
<u>3. Proportion</u>
Set the proportion and solve for x:

Answer: 12 tickets
