Andrea spent $26 for two adult tickets to the Dallas zoo the next month she spent $52 for four adult tickets does she spend the same amount per ticket each time

yes she does. if it is $13 a ticket because 13 + 13 = 26 then you multiply 13*4=56 which the four represents the amount of people and 13 is the amount of money she spends. So Andrea does spend the same amount of money on all of the tickets.
