Answer:
You will need to make 3 transactions
Step-by-step explanation:
For the first one you will do 22 times 3 people which is 66 plus 10 which is 76. For the second one you will do 20 times 3 people which is 60 plus the 16 dollar which gives you 76. So 3 people have to buy tickets for the two companies to have the same price.
