    A green flag costs ten times the price of a blue flag. A red flag costs half the price of a green flag. An orange flag costs ten dollars less than a red flag. If the four different color flags cost a total of 200 dollars, what is the price of an orange flag?

    blue flag = x
    green flag= 10x
    red flag = 5x (10x/2)
    orange flag = 5x-10
    total = 200

    so....

    x +10x + 5x + 5x - 10 = 200
    21x - 10 = 200
    21x = 210
    x = 10

    so blue flag = x = 10
    orange flag = 5x - 10 = 5*10 -10 = 50 - 10 = 40
