Adult= A
Children= C
First equation:
A+C= 11
A= 11-C
Second equation:
228 total price includes 22dollar x adult and 15dollar x children ticket price. Write the equation:
228= 22A+15C (substitute above value for adult)
228= 22(11-C) + 15C
228= 242-22C+15C
228 - 242 = 7C
14 = 7C
C= 2 (there are 2 children in the group)
Find adult number, using 11= A+C equation,
11= A+2
A= 9
Check: (9x22) + (2x15) = 228
198 + 30 = 228
They are :
-3, -2, -1, 0, 1 and 2
