    Answer:

    $532

    Step-by-step explanation:

    Hey There!

    So to solve this problem the first thing that we want to do is find the cost of 1 ball

    To do so we divide the total cost of 10 balls by 10

    280/10=28 so each ball cost 28

    now to find the cost of 19 balls we multiply the cost of 1 ball by 19

    18×28=532

    thus meaning 19 balls cost $532
