Tickets to a festival cost $7.00 each, and lunch costs $13.00 per person. renting a bus to and from the festival costs $63.00. which expression gives the cost of x people going to the festival?

20x+63

Step-by-step explanation:

add all of the multiplying factors which increase at the same rate, in this case it is 7.00 a ticket and 13.00 for food per person, making it 20.00 per person. Then place your variable next to that to signal the solver they are multiplying them, finally adding the 63.00 because they only need one bus and it isn't multiplying by the number of people.
