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?
+36915 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
