Part A Easton went to a concert with some of his friends. The tickets cost $29.50 each, and they spent a total of $15 on parking. The total amount spent
was $133.

C. 29.50p + 15 = 133

Step-by-step explanation:

p is the number of people going to concert

so the total cost of tickets: $29.50 times the number of people = 29.50p

and add the parking cost $15

so the total is 133 = 29.50p + 15 or 29.50p + 15 = 133

The question was cut off.  I'm assuming the missing information added $15 charge, for something.  Parking, I'll assume.  Part B is cut off.

Step-by-step explanation:

Total expense would be the number of people, x, times the ticket price for each:  

29.50x

But we need to add the $15 for parking (?):

29.50x + 15

This added to $133:

29.50x + 15 = 133     Option C

x = 4 tickets  [4*29.50 = 188.  Then add the $15 to reach $133]
