    The answer to your question is adult = $12, children = $10

    Step-by-step explanation:

    Data

    Family 1 Family 2

    2 adult + 4 children = $64 1 adult + 3 children = $42

    adult cost = a = ?

    children cost = c = ?

    Process

    1. - Write two equations to solve this problem

    2a + 4c = 64 Equation l

    a + 3c = 42 Equation ll

    2. - Solve the system of equation by elimination

    -Multiply equation ll by - 2

    2a + 4c = 64

    -2a - 6c = - 84

    0 - 2c = - 20

    c = - 20/-2

    c = 10

    3. - Substitute c in equation ll to find a

    a + 3 (10) = 42

    a + 30 = 42

    a = 42 - 30

    a = 12

    4. - Conclusion

    the cost for adult is $12 and the cost for adults is $10
