================================================================
Various conditions greatly affect this proportion. One of these is the
rise and fall of the food cost. Theoretically, the buyer should adjust
this difference in the food cost rather than increase her expenditures.
For instance, if in a certain year, the general cost of food is 20 per
cent. greater than it was in the preceding year, the housewife should
adjust her plan of buying so that for the same amount of money spent in
the previous year she will be able to supply her family with what they
need. Of course, if there is an increase in the income, it will not be
so necessary to work out such an adjustment.
22. ECONOMIES IN PURCHASING FOOD.--Through her study of the preceding
lessons, the student has had an opportunity to learn how to care for
food in order to avoid loss and waste, how to prepare it so that it may
be easily digested and assimilated, and how to make it appetizing and
attractive so that as little as possible is left over and none is
wasted. She should therefore be thoroughly acquainted with the methods
of procedure in regard to all such matters and should have worked out to
her satisfaction the best ways of accomplishing these things to suit her
individual needs.
