We are currently producing Product Z using a very
labor-intensive method. The selling price of Product Z
is $30 per unit, the variable expenses are $19.60 per unit, and the
fixed expenses are $1,820,000 per year. I am wondering if it
wouldn’t be better for us to automate the process for Product
Z. If we do, the variable expenses will drop to $16.00
per unit but the fixed expenses will increase to $2,940,000 per
year. The selling price will remain unchanged at $30...

test of the submarine at high pressures and why (consider the worst
case scenario).
