You can put this solution on YOUR website!
Jemima wants only whole numbers of bags.
c, bags of chocolate chips
w, bags of walnuts


Try accounting for the mass and for the cost.

MASS:
%283%2F4%29c%2B%281%2F4%29w=3

COST:
Remember, c and w are counting the numbers of BAGS. The prices are given to include per bag.
3c%2B2w%3C=15


Be sure that discussion makes sense before continuing.


Ready?.....

Simplification allows for easy use of Elimination Method part way through.
I found highlight%28w=c=3%29, three bags of each item.
