Q$1.$ Carrefour wants to launch its brand of in$-$store$-$grown

organic lettuce in small bags. The supermarket has two options

for processing harvested lettuce: manual processing $($say A$)$ and

mechanized processing $($say B$).$ The manual process will incur a

monthly processing cost of $$1500$ and a variable cost of $$2$ per

bag, while the mechanized process will incur a monthly

processing cost of $$1040$ and a variable cost of $$1\mathrm{.}50$ per bag.

Besides, the mechanized process needs a recyclable bag costing

$$\frac{0\mathrm{.}25}{?}$ bag to Carrefour. The store expects to fix the price at $$5$

per bag, irrespective of the processes.

a$)$ What is the breakeven volume for the manual process?

Also, find the breakeven point in dollars.

b$)$ What is the breakeven volume for the mechanized

process? Also, find the breakeven point in dollars.

c$).$ Which process will you use if you expect sales of $600$

bags monthly? Also, provide the opportunity loss of profit

if the store does not determine the better method.

d$)$ At what sales volume is the profit from the sales made

from the mechanized process more than the profit from the

sales made from the manual process by $$710?$

e$)$ Find the bags of sales both processes such that the manual

method has $500$ bags more than the mechanized method,

and the profit of the mechanized process is $$790$ less than

the manual process.
