dumbcow · Answer

set up inequalities Let x be pineapple juice, y be papaya juice x>=4 y >=4 9 < x+y < 15 --> 9-x < y < 15 -x just pick (x,y) combinations that satisfy these conditions

anonymous · Answer

Would these work ? 4 + 6 = 10 : (4 , 6)
4 + 7 = 11 : (4 , 7)
4 + 8 = 12 : (4 , 8)
4 + 9 = 13 : (4 , 9)

yep all of those would work
