Answer: Hello there!
we know that the zoo had an equal number of visitors on Saturday and Sunday, if the total number of visitors in the weekend is 32096, then the visitors in each day are: 32096/2 = 16048.
a) on Saturday, 1/8 of the people who visited were senior citizens, 1/8 were infants, 1/4 were children, and 1/2 were adults.
if we want to know the amount of each, then:
the amount of senior citizens are: (1/8)*16048 = 2006
the amount of infants are: (1/8)*16048 = 2006
the amount of children is: (1/4)*16048 = 4012
the amount of adults are: (1/2)*16048 = 8024
b) On Sunday, 1/16 of the people who visited were senior citizens, 3/16 were infants, 3/8 were children, and 3/8 were adults.
the amount of senior citizens are : (1/16)*16048 = 1003
the amount of infants are: (3/16)*16048 = 3009
the amount of children is: (3/8)*16048 = 6018
the number of adults is also: (3/8)*16048 = 6018
