Accepted Solution

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.
