As the cost of admission for an adult is A, the total cost for 1 adult = 1A, or A
As the cost of admission for a child is C, then total cost for 4 children = 4C
As total cost for an adult and 4 children is $85, then A + 4C = 85 ------ eq (i)
Likewise, cost of admission for 3 adults = 3A, and cost of admission for 2 children is 2C
Therefore, 3A + 2C = 105 ------- eq (ii)
- 3A - 12C = - 255 ------- Multiplying eq (i) by - 3
Therefore, we have:
- 10C = - 150 ------ Adding eqs (iii) & (ii)
C, or admission cost for a child = , or $
Substitute 15 for C in eq (i) and determine the admission cost for an adult.
Thereafter, do a check to make sure the answers are correct and make sense.
