My best friend of almost 40 years is a carpenter and owns his own contracting business, raking in around 3oo g’s a year with his 10th grade education.
There is no need to teach him to use geometry to find C when he can do so much faster with a framing square. Algebra isn’t needed to figure square footage or payroll.
I'm hiring a crew for a temporary job. Should I hire 10 less experienced people at $12/hr or should I hire 8 more experienced people who are 20% more productive at $15/hr?
My work truck gets 20 mpg. Along with insurance and depreciation, how much should I charge per mile for work related travel? How much should I charge if the price of fuel increases by 3%?
I could go on...
