present ratio of white :striped = 16:8 = 2:1
white added = x
striped added = 132-x
(16 + x)/(8 + 132-x) = 2/1
16+x = 16 + 264 - 2x
3x = 264
x = 88
he should add 8 whites and 44 whites
check:
new whites = 16+88 = 104
new stripes = 8+44 = 52
104:52 = 2:1
white added = x
striped added = 132-x
(16 + x)/(8 + 132-x) = 2/1
16+x = 16 + 264 - 2x
3x = 264
x = 88
he should add 8 whites and 44 whites
check:
new whites = 16+88 = 104
new stripes = 8+44 = 52
104:52 = 2:1
