Answer:

266 tickets

Step-by-step explanation:

Ratio of adult tickets to child tickets is 4 : 3

So, if we think of these as "parts", there are 4 parts adult tickets and 3 parts child tickets.

In total there is:

4 + 3 = 7 parts

Now, given 152 adult tickets. If there are 4 parts of adult tickets, how much is each part worth?

152/4 = 38

Total amount of tickets is 7 of these "parts", so total number of tickets is:

38 * 7 = 266 tickets
