Answer:
420 $40 tickets.
Step-by-step explanation:
Here is the explanation.
1. As 700 tickets cost a total of $33600, the average cost of each ticket is $48.
2. As there are 700 total tickets with each costing $40 or $60, we can use the total cost ($33600) to define the amount of each ticket.
3. If there were to be 420 $40 tickets, there will be 280 $60 tickets.
4. This means that the cost of each price of tickets ($40 and $60) will be distributed evenly among the total price, each costing $16800.
5. 420 x 40=16800 280x60=16800
6. There are 420 $40 tickets sold at the concert.
