I am looking for the formula used to work out the answer to this question?
One week the company received an order for tables with chairs and they needed to
produce exactly 4 chairs per each table produced. To produce a single chair one hour of
machine time and 2 kg of wood is necessary. When production was to take place the
company had only 328 kg of wood (instead of usual 345 kg). How many chairs, tables and
wardrobes should the company produce if they want to use up all the wood and all the
machine hours available?
