Description
Max was on vacation twice as long as Jared and Half as long as Wesley. The boys were on vacation a total of 3 weeks. How many days was each boy on vacation?
Explanation & Answer
So your equations are M=2J, 2M=W, and M+J+W=21days(3 weeks)
So substituting M and W into M+J+W=21 gives you 2J+J+2M=21, substitute M again, to get 2J+J+4J=21 so you get 7J=21 so J= 3 days.
