    Answer:

    Number of adult tickets = 180

    Number of child tickets = 165

    Step-by-step explanation:

    Given:

    Total number of ticket = 345

    Total amount = $1,395

    Cost of adult ticket = $5

    Cost of child ticket = $3

    Find:

    Number of child and adult tickets

    Computation:

    Assume;

    Number of child tickets = a

    Number of adult tickets = b

    So,

    a + b = 345………..eq 1

    3a + 5b = 1,395………..eq2

    3 x in eq 1

    3a + 3b = 1,035………eq3

    eq2 – eq3

    2b = 360

    b = 180

    Number of adult tickets = 180

    a + b = 345

    a = 165

    Number of child tickets = 165
