The jurassic zoo charges $10 for each adult admission and $8 for each child. The total bill for the 139 people from a school trip was $1174.How many adults and how many children went to the zoo?

adults=31, children = 108

Step-by-step explanation:

a + c = 139 equation 1

10a + 8c = 1174 equation 2

a=139-c isolate a from equation 1

10(139-c) + 8c = 1174 substitute a value into equation 2

1390-10c + 8c = 1174

-2c = -216

c = 108

use value of c in either equation to find value of a

a + c = 139

a + 108 =139

a = 31
