“A car manufacturer produces two versions of its popular medium sized model: a

hatchback aimed at the family market and a coupe designed to appeal to affluent

single customers.
Both are based on the same chassis and differ only in the body kit used to make

up the cars. They are both produced at the same factory.
There are 95,000 hours of manpower and 8,900 basic chassis units (one per

vehicle) available each week. The hatchback takes 4 hours of assembly time

while a coupe takes 6.5 hours.
At least 1,000 coupe models should be produced per week.
Production is also constrained by the fact that owing to problems with a supplier

only 34,000 door handles are available per week. A hatchback uses ten of these

handles while a coupe uses four.
The profit to the factory on a hatchback model is estimated to be £3,450 while the

profit on a coupe is £975.
The market demand for the cars is high. It is known that demand will exceed

production for time to come so they should be able to sell whatever mix of cars is

produced.
The car manufacturer wants to maximise its profits, but doesn’t know what

combination of versions of its medium-sized model to produce.”

My question is how can I answer Step 7? I don't understand how to arrange the values.
