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

thank you. appreciate it

We’ve been on the Internet for over 20 years doing just one thing: providing career information for free or at cost. We do this because we believe that the health education process is too expensive and too competitive.

We believe that all students deserve the same access to high quality information. We believe that providing high quality career advice and information ensures that everyone, regardless of income or privilege, has a chance to achieve their dream of being a doctor.
