Question 1171315
.
<pre>

 x = almond cookies

3x = chocolate cookies.


From the condition, we have THESE two equations


    x = 3n + 3     (1)    (n = the number of friends)

   3x = 4n + 24    (2)


Multiply equation (1) by 3 (both sides). You will get

    3x = 9n + 9.


Substitute it into equation (2).  You will get

    9n + 9 = 4n + 24.


It implies

    9n - 4n = 24 - 9

      5n    = 15

       n    = 15/5 = 3.


So, there are 3 friends.


By knowing it, <U>CAN YOU</U> answer the last question <U>on your own</U> ?

Solved.
