A:

ANSWER: The Jurassic zoo charges $12 for each adult admission. hence 25 adults and 51 children visited the zoo.
SOLUTION:
Given, the Jurassic zoo charges $12 for each adult admission and two dollars for each child.
The total bill for the 76 people for the school trip was $402 We need to find how many adults and how many children went to the zoo.
Let the number adults visited zoo be x
And the number of children visited the zoo be yThen, x + y = 76 --- (1)
For 76 people, the total bill was 402. Hence we get,
12x + 2y = 402 ---- (2)
Now multiply eqn (1) with -2
-2x -2y = -152 ---- (3)
Now, add equation 2 and 3
10x + 0 = 250
x = 25
Now substitute x value in (1)
25 + y = 76
y = 76 – 25
y = 51
Hence, 25 adults and 51 children visited the zoo.
