    Answer: an adult ticket costs $25 and a child ticket costs $21

    Step-by-step explanation:

    Let x represent the price of an adult ticket.

    Let y represent the price of a child ticket.

    Richard purchased air show tickets for 5 adults and 2 kids. The total cost is $167. This is expressed as

    5x + 2y = 167- – – – – – – – – – -1

    The cost for a child is $4 less then the cost of an adult ticket. This is expressed as

    y = x – 4

    Substituting y = x – 4 into equation 1, it becomes

    5x + 2(x – 4) = 167

    5x + 2x – 8 = 167

    7x = 175

    x = 175/7

    x = 25

    y = x – 4 = 25 – 4

    y = 21

    Answer:

    adult ticket – $25

    child ticket – $21

    Step-by-step explanation:

    if there are 5+2 tickets and it equals 167 in total then the equation is 5x+2y=167. and y=x-4 so the updated equation is 5x+2(x-4)=167

    5x+2x-8=167

    7x-8=167

    7x=175

    x=$25

    one adult ticket is $25

    then y=x-4 and y is a child ticket. so y=25-4

    y=$21

    one child ticket costs $21
