Allegations: Total Parts
Parts needed of higher % + parts needed of lower %
Allegations: Amount of higher % needed (volume or weight)
Total parts= parts needs of higher %/total parts * desired volume or weight
Allegations: Amount of lower % needed (volume or weight)
Total parts = Parts needed of lower %/total parts * desired volume or weight
