            potato       brinjal      tomato
PRICE        2            1.5         0.50
Qnty          p             b           t
COST         2p           1.5b        0.5t


Material account: p%2Bb%2Bt=10

Cost account: 2p%2B1.5b%2B0.5t=10%2A10;
4p%2B3b%2Bt=200

System is system%284p%2B3b%2Bt=200%2Cp%2Bb%2Bt=10%29
Multiple solutions because more variables than equations.
