9 tickets would cost $45 on Friday.

Since 3 tickets cost $21, hence the cost of each ticket is:

Cost of each ticket = $21 / 3 tickets = $7 per ticket

On Fridays, all tickets are discounted by $2, hence:

Cost for each ticket on Fridays = $7 - $2 = $5

The cost of 9 tickets on Friday = $5 per ticket * 9 tickets = $45

Hence 9 tickets would cost $45 on Friday.
