Hakim had 400 sticks of chicken satay and mutton satay altogether. After selling 1/9 of the chicken satay and 15 sticks of muttom satay, he had 4 times as many chicken satay as mutton satay left. How many sticks of chicken satay did Hakin have left?

c + m = 400

  or

c = 400 - m

 

selling 1/9 leaves 8/9

   8/9 c  = 4 ( m-15)

  8/9 ( 400-m)  = 4m - 60

  8/9 (400) - 8/9 m = 4m - 60

   m=85         then     c = 315            only  8/9 of the 315 is left = 280 chicken sticks
